The movement's founder, the Mahdi Ibn Tumart, became known as \"the man of the square dirham\".[6](https://www.jerez.es/en/webs-municipales/archaeological-museum/collection/selection-of-pieces/piece-detail/dirham-cuadrado) Salvador Fontenla Ballesta argues that Ibn Tumart never struck gold but probably did strike silver dirhams, citing a late report identifying him with \"the lord of the square dirham\" and the fact that Abd al-Mu'min put no name of his own on the silver, apparently respecting the type the Mahdi had put in circulation.[7](http://hdl.handle.net/10261/9828) The author of the same study argues the opposite: that Ibn Tumart, as mahdi occupying the place of the Prophet, had no reason to strike coin at all, since the Prophet did not, and that the first Almohad coinages belong to the reign of Abd al-Mu'min.[7](http://hdl.handle.net/10261/9828) Surviving half-dirhams of Abd al-Mu'min ibn Ali (1130–1163) are recorded in museum collections.[3](https://www.khalilicollections.org/islamic-coins/7374-almohad-silver-square-dirham-nm-nd/)\n\n## Contents: inscriptions and design\n\nThe dirham's legends were entirely religious. On the ARQUA museum specimen from Cordoba the reverse reads \"God is our Lord / Muhammad is our prophet / The Mahdi is our Imam\" and the obverse \"No god but God / all power is God's / no strength except in God\".[4](https://ceres.mcu.es/pages/Main?idt=30363&inventary=100642&museum=ARQUA&table=FMUS) \n\nThe design removed the features that had identified earlier [Andalusi coinage](https://www.edgepedia.org/andalusi-coinage). With the Almohads, the mention of the year was eliminated, the mint was marginalized or omitted, the religious legend was adapted to Almohad orthodoxy, the dirham became anonymous, and it abandoned the traditional circular form for the square.[4](https://ceres.mcu.es/pages/Main?idt=30363&inventary=100642&museum=ARQUA&table=FMUS) The texts were written in a clear, simple cursive naskh script.[2](https://islamicart.museumwnf.org/database_item.php?id=object%3BISL%3Bma%3BMus01_F%3B8%3Ben)\n\n## Implementation and revision\n\nA recorded Cordoba specimen weighs 1.40 g, with a maximum diameter of 14 mm.[4](https://ceres.mcu.es/pages/Main?idt=30363&inventary=100642&museum=ARQUA&table=FMUS) Because the same legends repeat on later Nasrid and Marinid coinage, and the pieces lack mint and date, their dynastic and chronological attribution is difficult.[1](http://hdl.handle.net/10261/25692) Almohad coins in general lack dates, which makes precise chronology difficult; gold can be assigned by the caliph's name as amir al-mu'minin ('Commander of the Faithful', caliph's title), silver only broadly.[7](http://hdl.handle.net/10261/9828) Sources note the high rank of the officials in charge of the mint, an indication of the importance the Almohads gave to their numismatic renewal for spreading their own slogans.[9](https://pdfs.semanticscholar.org/e4a2/5b28d31778363621378b25e13bd4a02830d9.pdf)\n\nThe type outlived its issuers. The related gold masmudiyya coins were much sought after in the Catholic states of Spain for their weight and the purity of their gold, and continued to be used in exchanges even after the fall of Almohad rule.[2](https://islamicart.museumwnf.org/database_item.php?id=object%3BISL%3Bma%3BMus01_F%3B8%3Ben)\n\n## Political influence\n\nThe square-in-circle design became the Almohads' recognizable signature and then an international monetary type. The motif of a square within a circle, combined with naskhi script, was the immediately recognizable signature of the Almohad rulers on their coins; it was first imitated in the Ayyubid Near East for economic and political reasons, and then widely adopted as far as Afghanistan and India under the [Ghurids](https://www.edgepedia.org/ghurids) and the Sultans of Delhi.[5](https://isidore.science/index.php/document/10.3406/anisl.2011.1650) Cecile Bresc, who studies this diffusion in the thirteenth-century [Muslim world](https://www.edgepedia.org/muslim-world), notes that on medieval Muslim coins the association of legends and geometric motifs defines and signs the monetary type, but that imitation and diffusion of a type blurs the identification of the issuing power.[10](https://www.persee.fr/doc/anisl_0570-1716_2011_num_45_1_1650) The design combining squares and circles spread from the western Islamic realm into the eastern one, where it lasted for centuries.[11](https://riuma.uma.es/xmlui/handle/10630/35377)\n\nThe type also crossed the religious frontier. Christian imitations of the Almohad dirham, known as millares, were struck in Aragon and southern France for use in trade with the Muslim states of North Africa, and circulated throughout the Mediterranean including the [Iberian Peninsula](https://www.edgepedia.org/iberian-peninsula).[12](https://www.academia.edu/111070823/Los_millareses_y_otras_copias_del_d%C3%ADrham_almohade)\n\n## Reception and assessment\n\nHistorians read the coinage as an instrument of Almohad ideology. Coin types and legends express the religious, political, and economic position of the issuing power, and the Almohad reform used new shapes, metrology, and legends to transmit the movement's messages.[9](https://pdfs.semanticscholar.org/e4a2/5b28d31778363621378b25e13bd4a02830d9.pdf) The Jerez Archaeological Museum attributes the large religious legends on both faces to the movement's extreme orthodoxy.[6](https://www.jerez.es/en/webs-municipales/archaeological-museum/collection/selection-of-pieces/piece-detail/dirham-cuadrado) One scholarly explanation holds that the square coins may have been regarded as protective objects, and that the square shape of Quran copies in the Almohad and post-Almohad period points to the cubical shape of the Ka'ba, giving the coinage a sacred geometrical symbolism.[11](https://riuma.uma.es/xmlui/handle/10630/35377)\n\nOn the question of licitness, [Ibn Hazm](https://www.edgepedia.org/ibn-hazm) held that striking coin was religiously illicit and that Muslims should transact with uncoined gold and silver ingots by weight, a doctrine recorded in his Siyasat al-imam wa-tadbir al-mamlaka and rebutted by the Ceutan ruler Abu al-Abbas al-Azaf (557/1162–633/1236). Salvador Fontenla links this doctrine to Almohad monetary policy, suggesting that the square form, the absence of dating, and the weight changes may have been designed so the coins would not look like struck coin, equating them with weights.[7](http://hdl.handle.net/10261/9828)\n\n## References\n\n1.
