Lewis Henry Morgan and Unilineal Evolutionism: Ancient Society, Kinship Systems & UPSC 15-Marker Answer

1. Introduction: Lewis Henry Morgan and 19th-Century Evolutionism

Lewis Henry Morgan (1818–1881), an American lawyer and ethnologist often hailed alongside E.B. Tylor as one of the founding fathers of modern anthropology, was the primary architect of 19th-century Classical Unilineal Evolutionism. Operating under the intellectual currents of the Victorian Enlightenment and Darwinian biological evolutionary theory, Morgan sought to uncover universal historical laws governing the development of human culture, institutions, and social structures.

Morgan’s paradigm rested on the foundational assumption of the Psychic Unity of Mankind (proposed by Adolf Bastian)—the premise that the human mind operates under identical cognitive, psychological, and physiological principles worldwide. Consequently, he argued that all human societies necessarily progress along a single, unvarying, upward evolutionary ladder: from crude beginnings through uniform stages to reach higher forms of civilization. Within the UPSC Anthropology Optional Syllabus (Paper 1, Unit 6 - Anthropological Theories), Morgan’s evolutionary stages, his foundational contributions to kinship systems, and the Marx-Engels appropriation of his work form a recurring high-yield theme tested across 10-marker, 15-marker, and 20-marker questions.

2. Universal Evolutionary Schema: Ancient Society (1877)

In his landmark treatise, Ancient Society: Or Researches in the Lines of Human Progress from Savagery through Barbarism to Civilization (1877), Morgan formulated a comprehensive tripartite schema dividing human cultural progress into three grand ethnical periods: Savagery, Barbarism, and Civilization. He further subdivided Savagery and Barbarism into Lower, Middle, and Upper sub-periods, using breakthroughs in subsistence technology and material inventions as the objective criteria demarcating each stage.

Ethnical Period	Technological & Material Criteria	Social, Marriage & Kinship Form
1. Lower Savagery	Infancy of the human race. Subsistence based on wild fruit and nut gathering; emergence of articulate speech.	Promiscuous intercourse; absence of formal marriage codes or regulated family units.
2. Middle Savagery	Discovery of fire and the invention of fish subsistence; expansion across geographic territories along coastlines and rivers.	Consanguine Family: Group marriage organized along generational lines (incest taboo between parents and children).
3. Upper Savagery	Invention of the bow and arrow; development of sophisticated hunting technology and wooden implements.	Punaluan Family: Prohibition of marriage between brothers and sisters; emergence of the matrilineal gens (clan).
4. Lower Barbarism	Invention and application of the art of pottery and ceramic manufacture.	Syndyasmian (Pairing) Family: Loose union of male and female without exclusive cohabitation; easily dissolved by either partner.
5. Middle Barbarism	Domestication of animals in the Eastern Hemisphere; cultivation of maize and plants via irrigation and adobe/stone architecture in the Western Hemisphere.	Consolidation of clan systems; shifting lineage dynamics as pastoral wealth concentrates in male hands.
6. Upper Barbarism	Smelting of iron ore and the production of iron tools, plows, and weapons.	Patriarchal Family: Authority vested in male head; institutionalization of polygyny and domestic authority over wives and slaves.
7. Civilization	Invention of the phonetic alphabet and the production of written records; urban industrial development.	Monogamian Family: Exclusive cohabitation, individual private property rights, and state-backed legal inheritance codes.

3. The Genesis of Kinship Studies: Systems of Consanguinity and Affinity (1871)

Beyond his evolutionary stages, Morgan is universally celebrated as the founder of anthropological kinship studies. Through extensive empirical investigations among the Iroquois (Haudenosaunee) tribes of upstate New York—published in League of the Ho-dé-no-sau-nee, or Iroquois (1851) and later in his comparative global survey Systems of Consanguinity and Affinity of the Human Family (1871)—Morgan established that kinship terminologies reflect historical systems of social and marital organization.

Morgan's Dual Kinship Classification:

+-------------------------------------------------------------+
|           1. CLASSIFICATORY KINSHIP SYSTEMS                |
|  • Merges lineal relatives with collateral relatives.        |
|  • E.g., Father and Father's Brother addressed by SAME term. |
|  • Found in tribal/clan societies with collective solidarity.|
+-------------------------------------------------------------+
                                  |
                  [Evolution Driven by Property Rights]
                                  v
+-------------------------------------------------------------+
|            2. DESCRIPTIVE KINSHIP SYSTEMS                  |
|  • Explicitly separates lineal from collateral relatives.   |
|  • Distinct terms for Father, Uncle, Mother, Aunt.           |
|  • Emerges alongside private property, monogamy & state laws. |
+-------------------------------------------------------------+

Evolution from Societas to Civitas

Morgan traced the macro-evolution of human political organization through two fundamentally distinct institutional paradigms:

• Societas (Gens / Clan-based Society): The ancient form of governance rooted in personal relations, kin lineages (gens, phratry, tribe), democratic councils, and communal property. Decisions were made collectively, and status was determined by lineage standing.
• Civitas (Political / State Society): The modern territorial state founded on geographic location, administrative districts, individual private property ownership, and formal judicial laws. Civil society superseded kinship ties as the basis of political obligation.

4. Marxist Appropriation: Engels and The Origin of the Family (1884)

Morgan’s materialist insights exerted an immense influence on Karl Marx and Friedrich Engels. After reading Morgan's Ancient Society, Marx took detailed notes, which Engels synthesized into his seminal 1884 text, The Origin of the Family, Private Property and the State:

• Primitive Communism: Engels utilized Morgan’s ethnographic description of the matrilineal Iroquois to prove that private property, class oppression, and the nuclear family are not eternal human institutions. For millennia during Savagery and early Barbarism, human societies practiced communal ownership of land and collective domestic production.
• The World-Historical Defeat of the Female Sex: Engels argued that the transition from Barbarism to Civilization—driven by the domestication of animals, metal metallurgy, and accumulation of private property in male hands—overthrew ancient matrilineal clan law, establishing patrilineal inheritance, female subordination, and monogamy (to ensure legitimate heirs for property transmission).

5. Critical Evaluation and Methodological Limitations

While Morgan provided the scaffolding upon which later anthropological theory developed, 20th-century field anthropologists subjected unilineal evolutionism to extensive critique:

• The Boasian Empirical Critique: Franz Boas and his students (Historical Particularism) demonstrated that human societies do not develop along a unilineal sequence. Numerous cultures skipped stages (e.g., African societies moving straight from stone implements to iron smelting without an intermediate bronze age) through cultural diffusion rather than independent invention.
• Faulty Evolutionary Assumptions on the Family: Ethnographic fieldwork proved that primitive promiscuity and universal ancient matriarchy were theoretical constructs rather than empirical facts. Many of the simplest hunting-gathering bands (such as the Andamanese, Australian Aborigines, or Inuit) practice monogamous pair-bonding without prior stages of group marriage.
• Ethnocentric Victorian Bias: Morgan placed Victorian European society and private property as the apex of human achievement, evaluating other civilizations through an ethnocentric benchmark.
• Lasting Legacy: Despite these shortcomings, Morgan introduced empirical rigor to kinship analysis, inspired 20th-century Neo-Evolutionism (Leslie White, V. Gordon Childe), and established material subsistence as a critical variable in cultural development.
