Definition
Mohammedan Law, as used in Anglo-American legal dictionaries, refers to the body of religious and customary law derived from Islamic jurisprudence (fiqh) that was recognized and applied by British colonial authorities in India to govern Muslims in matters of personal status — principally family relations, inheritance, marriage, divorce, and religious endowments. The term is a colonial-era designation for what is more accurately called Islamic law or, in its classical jurisprudential form, Sharia (Arabic: شريعة) as elaborated through the major schools of Islamic legal thought.
In British India, Mohammedan Law operated as a personal law system: a Muslim litigant's rights in family and succession matters were determined by this body of law rather than by general territorial law. British courts administered it alongside Hindu Law, which applied to Hindu subjects, under a framework sometimes called the "personal law" or "religion-based law" model of colonial governance.

Common Language
Wiktionary: "Mohammedan" is an archaic or offensive term for a Muslim, a follower of Islam. Its use as an adjective to describe law, practice, or persons is now considered outdated and, in many contexts, pejorative.
Webster's 1913: "Mohammedan" — Of or pertaining to Mohammed, or the religion and institutions founded by Mohammed.
Editorial note: The common-language word is now widely rejected as a label for Muslims and Islamic practice, because it implies that the religion centers on the prophet Mohammed rather than on God (Allah), which Muslims consider theologically inaccurate. Legal researchers must recognize that the historical dictionary term is simply how 19th- and early 20th-century Anglo-American legal sources labeled Islamic law applied in colonial India. The substance being described — Islamic jurisprudence as applied through British courts — is real and important; the label is a product of its era and should not be reproduced in modern legal writing.

Common Confusion
Mohammedan Law (as used in Anglo-Indian legal sources) is frequently confused with three related but distinct concepts:
1. Sharia broadly: Sharia encompasses the full range of Islamic religious obligation — prayer, diet, ritual, ethics, and law. Mohammedan Law as applied by British courts was a narrow, court-enforceable subset, heavily mediated by British evidentiary and procedural rules and often filtered through English translations of classical texts (particularly Hamilton's translation of the Hedaya). It was not Sharia in its complete theological sense.
2. Anglo-Muhammadan Law: Scholars use this term to describe the hybrid body of doctrine that actually emerged from British Indian courts — a fusion of classical Islamic sources, colonial judicial interpretation, and English common law reasoning. What British courts called "Mohammedan Law" was, in practice, Anglo-Muhammadan Law: shaped by British judges who often misread or selectively applied classical sources.
3. Modern Islamic Law as applied in contemporary Muslim-majority jurisdictions: The doctrine, schools, and codifications operating today in countries such as Pakistan, Malaysia, or Egypt differ substantially from the 19th-century Anglo-Indian construction. Researchers should not treat Black's or Bouvier's definitions as describing either classical fiqh or contemporary Islamic family law.

Why It Matters in Research
This term is a research gateway, not a finished concept. Several traps await the unwary researcher:
Terminological evolution is sharp. Sources from 1800 through roughly 1950 use "Mohammedan Law" as standard. Mid-20th-century sources shift toward "Muslim Personal Law." Contemporary scholarship uses "Islamic law," "fiqh," or jurisdiction-specific terms (e.g., "Muslim Family Law Ordinance" in Pakistan). A corpus search on any single term will miss materials using the others.
The historical dictionaries are thin and India-specific. Both Black's editions and Bouvier define the term almost entirely by reference to British India. This is accurate to the term's use in Anglo-American legal literature but obscures the fact that Islamic law operated — and continues to operate — across dozens of jurisdictions from Morocco to Indonesia with significant doctrinal variation by school (Hanafi, Maliki, Shafi'i, Hanbali) and by local custom.
School-of-law variation matters enormously. British Indian courts applied predominantly Hanafi doctrine to Sunni Muslims (the majority), but other schools governed other communities. A research question about inheritance, divorce, or waqf (endowment) doctrine may turn on which school applied. Historical Anglo-Indian case law frequently obscures this.
The Hedaya problem. Hamilton's 1791 English translation of the Hedaya (a classical Hanafi text) was the primary reference used by British Indian courts for generations. That translation contains errors, anachronisms, and gaps that shaped Anglo-Muhammadan doctrine in ways that diverge from classical sources. Researchers using 19th-century case law or commentary should be alert to this mediation layer.
Bouvier's entry trails off mid-sentence (ending "See HIN—"), clearly a truncation pointing to a cross-reference to Hindu Law. This signals the comparative personal-law framework that organized British India's legal structure and is itself a research lead.
Post-colonial persistence. India's Muslim Personal Law (Shariat) Application Act of 1937 and subsequent legislation carried forward much of this framework after independence. Pakistan and Bangladesh developed distinct statutory regimes. Researchers tracing doctrine from the colonial period into contemporary South Asian law must track these legislative breaks carefully.

Historical Dictionary Support
All three sources — Black's (1st Ed.), Black's (2nd Ed.), and Bouvier's — offer nearly identical definitions: a system of native law prevailing among Mohammedans in India, administered by the British government. The uniformity is notable and telling. These dictionaries were not attempting to describe Islamic jurisprudence in any depth; they were flagging the term as it appeared in Anglo-Indian legal practice for the benefit of American practitioners who might encounter it in treatises, reports, or commercial correspondence.
What the historical sources agree on: the term is geographically bounded (India), institutionally bounded (British administration), and descriptive rather than analytical.
What the historical sources miss entirely: the internal doctrinal structure of Islamic law, the school variations, the classical textual tradition, the ongoing application of analogous frameworks in Ottoman, Egyptian, and other jurisdictions, and the colonial distortions introduced by English-language mediation of Arabic and Persian sources. They also do not address waqf law, Islamic criminal law (which British courts generally declined to administer), or the significant debates among Muslim scholars about the authenticity of the Anglo-Indian version of their law.
Bouvier's truncated cross-reference to Hindu Law is the most useful archival detail in any of the three entries. It confirms that for Bouvier's audience, "Mohammedan Law" was intelligible primarily in contrast to Hindu Law — two halves of the British personal-law system in India — rather than as a standalone jurisprudential tradition.

Jurisdictional Note
"Mohammedan Law" as a legal term of art is largely confined to British colonial and post-colonial South Asian legal contexts. Contemporary researchers working in Islamic family law in other jurisdictions — the Gulf states, Malaysia, Indonesia, North Africa, or diaspora Muslim communities in Western courts — will encounter different terminology, different institutional frameworks, and substantially different doctrine. The Anglo-Indian corpus is not a reliable guide to Islamic law outside its specific colonial context.
