# Tell Begum

Tell Begum, also called Gird-i Begum, is a multi-period archaeological mound in the Shahrizor Plain of the Kurdistan Region of Iraq, occupied from the Halaf period of the sixth millennium BCE through the Late Chalcolithic, with a newly identified Early Bronze Age phase of the early third millennium BCE.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The site is a key reference point for the chronology of northeastern [Mesopotamia](https://www.edgepedia.org/mesopotamia) because it carries a thick, radiocarbon-dated Halaf sequence and a Late Chalcolithic sequence that can be tied to neighboring dated sites.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup>

## Location and setting

Tell Begum sits on a [Pleistocene](https://www.edgepedia.org/pleistocene) terrace or natural levee in a landscape that may have been marshy in antiquity.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> The mound rises 21 meters above the plain and consists of a northern Upper Mound and a southern Lower Mound covering approximately 5 ha together; the trenches of the 1960 excavation remain visible as surface depressions.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup><sup> • </sup><sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup> The site lies about 560 meters east of the central part of Wadi Shamlu and is surrounded by a cluster of five small low-rise mounds, visible on [QuickBird](https://www.edgepedia.org/quickbird) satellite imagery, some of them small Halaf-period satellite settlements.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

## Excavation and exploration history

**1960 soundings.** Archaeological work began in 1960 in connection with the construction of the Darband-e Khan dam. An Iraqi team from Baghdad directed by Muhammad Ali Mustafa ran a four-week campaign, cutting a step-trench on the Upper Mound, and a sounding on the Lower Mound.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The Lower Mound trench measured 23 m long and 3 m wide and reached a depth of over 8 m, with twenty levels identified; the trench was not backfilled and the work remained largely unpublished.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> Ismail Hijara, in his 1997 book on the Halaf period in northern Mesopotamia, interpreted the site's unusual polychrome Halaf pottery as an intermediate Halaf-Ubaid Transitional stage.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

**2011 and 2013.** A Leiden University team directed by Olivier Nieuwenhuyse, working with the Directorate of Antiquities in [Sulaymaniyah](https://www.edgepedia.org/sulaymaniyah), conducted a systematic survey in 2013 using a 5 × 5 meter radial grid over the visible sherd scatter, together with small test excavations on both mounds.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> These investigations revealed a 5 ha site inhabited during the Halaf, Ubaid, Late Chalcolithic, and medieval periods, with the Halaf settlement possibly covering about 3 ha and representing a local variation of the [Halaf culture](https://www.edgepedia.org/halaf-culture).<sup>[4](https://discovery.ucl.ac.uk/id/eprint/1508024/)</sup> Datable sherds on the mound top included 'Kurdish Ware' and medieval pottery.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

**2022.** In summer 2022 a project based at the Freie Universität Berlin, in cooperation with the Directorate of Antiquities of Sulaymaniyah, began renewed excavations, reported in the journal *Iraq*.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> A German Research Foundation (DFG) project frames the site as a case study of mobile villages and dynamic landscapes, investigating mobility as a strategy of resilience for a settlement occupied from the mid-6th to the mid-4th millennium BCE.<sup>[5](https://gepris.dfg.de/gepris/projekt/424609853?language=en)</sup>

## Occupation sequence and chronology

**Halaf period.** The earliest occupation dates to the Halaf period, with about 6 m of accumulated Halaf deposits, which makes Tell Begum a major settlement of that period.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> [Radiocarbon dating](https://www.edgepedia.org/radiocarbon-dating) places the Halaf layer and its local pottery variant between 5600 and 5200 cal BC, overlapping the Halaf-Ubaid Transitional period in Upper Mesopotamia.<sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup> Three earlier radiocarbon results suggest ca. 5480–5200 cal BCE (2σ) for the Late Halaf to Halaf-Ubaid transitional phase; individual samples from Halaf Level IV calibrated to 5481–5329 BC (95.4%), 5387–5215 BC (87.5%), and 5479–5307 BC (94.6%).<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup> In the 1960 sounding, levels XX to IV, from the base to about 2.6 m below the surface, were dated to the Halaf period.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

**Ubaid and Late Chalcolithic.** Ubaid traces at the site are limited, though dark-painted Ubaid-related pottery was found at a height of approximately 16–18 m on the 21 m mound.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The Lower Mound was abandoned at the very end of the Halaf period and resettled in LC1, when the settlement perhaps reached its largest extent of about 5 ha; a one-meter-thick LC 1–3 deposit was documented on the Lower Mound atop the Halaf occupation.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The 2013 report provisionally dated the Late Chalcolithic occupation to the LC1–3 stages, c. 4300 to 3600 cal. BC, and concluded that after LC3 the entire mound was abandoned for a long period.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The 2022 excavations revised this picture: pottery analysis and radiocarbon dates indicate that the Upper Mound Late Chalcolithic strata span LC 3 to early LC 4, with modeled ranges overlapping [Kani Shaie](https://www.edgepedia.org/kani-shaie)'s LC 3 date of 3750–3650 BCE and LC 3–4 of 3650–3375 BCE.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> A 2.17 m height difference between the lowermost and uppermost strata in Upper Mound Units E and D implies relatively rapid accumulation of Late Chalcolithic strata.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup>

**Early Bronze Age and later.** The 2022 work on the Lower Mound brought to light a substantial, previously undocumented Early Bronze Age occupation phase in the early third millennium BCE, with modeled dates fitting Kani Shaie's 2900–2650 BCE.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> Later use was intermittent: Late [Bronze Age](https://www.edgepedia.org/bronze-age) and Ottoman pottery attest to activity after the main occupation, and traces of an Iranian army post were found close to the top of the Upper Mound.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

## Material record

The 1960 sounding produced the site's basic stratigraphy: above the Halaf levels lay a mixed level (III) with Halaf, Ubaid, and Uruk sherds, then an Uruk level (II) and an Islamic level (I).<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> A field note by al-Siwani records most Halaf sherds as recovered from a depth of 2.6–8.6 m, while re-excavation in 2013 found the Halaf cultural layer (Level IV) at 2.2–3.2 m below the surface, without reaching its base.<sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup>

**Halaf pottery.** The Shahrizor Plain lies at the easternmost distribution of Halaf pottery, and re-excavation showed that Halaf pottery there had unique local attributes, an 'east end' variant distributed across the Shahrizor and Pshdar plains.<sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup> This variant shows decorative similarities to White on Black Ware and J Ware in the Mahidasht Plain rather than to the transition to Ubaid style.<sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup>

**Late Chalcolithic pottery.** Grey Burnished Ware sherds and bevelled rim bowls suggest an LC3 date for the uppermost Late Chalcolithic strata. The site lacks typical 'southern later Uruk' elements such as wheel-made vessels, loop handles, and nose lugs, and also lacks Coba bowls and casseroles of the Post-Ubaid horizon.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> Chaff-Faced Ware finds comparisons at [Tell Brak](https://www.edgepedia.org/tell-brak), Tell Hamoukar, and Tell Feres al-Sharqi in northern Syria in the LC1–3 stages, anchoring Tell Begum in the northern Mesopotamian relative chronology.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

**Early Bronze Age architecture and burials.** Early Bronze Age architecture on the Lower Mound used plano-convex mud bricks and slightly curved, thick walls hinting at a round building comparable to Tell Razuk, Tell Gubba, and Tell Madhhur in the Hamrin region; the Early Bronze Age pottery parallels point mainly downriver towards the Hamrin basin.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> Three burials were found in 2022: one baby in a jar of probable LC 3 date and two in unadorned pits of probable Islamic date.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup>

## Tell Begum in the regional settlement system

With a minimum Halaf settlement size of approximately 3 ha, Tell Begum ranks as a medium-sized Halaf site, while its 6 m of Halaf accumulation makes it a major settlement of the period by that measure.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The five small surrounding mounds, some with small Halaf occupations, indicate a local cluster of satellite sites around the main mound.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> The absence of southern Uruk ceramic elements bears on the question of how far the Uruk expansion reached in the eastern foothills: the Late Chalcolithic assemblage connects northward to Syria rather than southward to the alluvium.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>

Comparison with the Rania plain to the north puts the site's scale in perspective. [Tell Bazmusian](https://www.edgepedia.org/tell-bazmusian), the largest site in the Rania plain, lies about 12 km south of Rania, covers an area some 1500 m in circumference, rises 23 m, and sits 800 m from the Zab river; its first excavation season ran from 10 July to 15 October 1956.<sup>[6](https://webhelper.brown.edu/joukowsky/resources/alsoof/files/9507529.pdf)</sup>

## By the numbers

- Mound height: 21 m above the plain.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>
- Maximum settled extent: about 5 ha in the Late Chalcolithic; Halaf settlement about 3 ha.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup><sup> • </sup><sup>[4](https://discovery.ucl.ac.uk/id/eprint/1508024/)</sup>

- 1960 Lower Trench: 23 m × 3 m, over 8 m deep, twenty levels.<sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup>
- Rapid Late Chalcolithic accumulation: 2.17 m between lowermost and uppermost strata in Upper Mound Units E and D.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup>
- Radiocarbon: eleven charred botanical samples submitted to the Poznań Radiocarbon Laboratory in 2022; Halaf dates ca. 5600–5200 cal BC.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[3](https://www.jstage.jst.go.jp/article/orient/57/0/57_113/_pdf/-char/ja)</sup>

## Recent developments

The report of the 2022 season changed the site's sequence in three ways. It confirmed Late Chalcolithic levels on the Upper Mound and narrowed them to LC 3 to early LC 4, later than the LC1–3 span proposed in 2013.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup><sup> • </sup><sup>[2](https://www.cambridge.org/core/journals/iraq/article/revisiting-tell-begum-a-prehistoric-site-in-the-shahrizor-plain-iraqi-kurdistan/ED6D44558C358BBCA172A6B72CFAFB29)</sup> It documented the Early Bronze Age phase on the Lower Mound, previously unknown at the site.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup> And it added the three burials and the traces of an Iranian army post near the mound top.<sup>[1](https://www.cambridge.org/core/journals/iraq/article/girdi-begum-report-on-the-2022-excavations/F6BF46765B1D5391A1C8F7A311F55D3B)</sup>
