Sr Antonio Frey Sanchez

Summary

The interview explores how climate can help explain historical change, particularly the rise of the Almoravids and the later crisis of the Almohads. Professor Antonio Frey Sánchez stresses that climate is one factor among many, alongside politics, religion, economics, and military events. It can shape the conditions in which societies act, but it does not determine history by itself.

Climate and the Rise of the Almoravids

• The discussion places the Almoravids’ emergence within the medieval warm period, whose climatic effects may have begun well before their political rise.
• According to Frey Sánchez, a wetter Sahel may have expanded grazing land and supported agriculture across parts of southern Morocco and farther south.
• Better food supplies could have contributed to population growth and increased numbers of camels and horses. Those resources, in turn, helped make trade and military expansion more feasible.
• Around the Almoravids’ rise in the mid-11th century, conditions appear to have been changing: the Sahel was becoming drier, while northern areas still had relatively favorable rainfall. The Almoravids’ movement north may therefore have been partly connected to shifting environmental conditions, as well as to religious, political, and strategic factors.
• The interview presents their expansion—from the Sahara and trans-Saharan trade centers toward Sijilmasa and Marrakech, and across the Strait of Gibraltar—as an example of how climate, agriculture, livestock, commerce, and state formation could interact.
• Archaeological evidence is described as broadly consistent with written accounts. For instance, declining water availability at Aoudaghost is associated with deeper wells, while water-management works in northern cities such as Sijilmasa and Marrakech point to different local conditions.

Trade, Settlement, and Prosperity

• The Almoravids connected trans-Saharan caravan trade with northern and maritime networks. Their expansion brought them into contact with both sub-Saharan trading centers and the ports and societies of the north.
• The discussion links agricultural and livestock productivity to population health and economic strength, while also emphasizing exchanges between nomadic and settled communities.
• The Almoravid state is described as becoming increasingly settled and administratively organized. Its currency, the dinar, is noted as an important and long-lasting feature of its economic influence.
• The speakers also discuss the Almoravids’ role in al-Andalus, including Granada, and compare the major Muslim dynasties associated with Córdoba, Seville, and Granada.

Climate and the Almohad Period

• The Almohads inherited and reshaped much of the political structure established by the Almoravids.
• The interview describes a sequence of environmental pressures and political upheavals. Reports of drought and famine in the Maghreb from the early 13th century are said to coincide with rebellions and civil conflict that weakened the Almohad Caliphate.
• The speakers also refer to severe weather and high mortality in Iberia around the Battle of Las Navas de Tolosa in 1212, including a period described in the General Chronicle of Castile as the “Black Biennium.”
• In the later 13th century, the pattern appears to shift: the Maghreb is described as experiencing more favorable harvests, while much of Europe faced colder conditions and crop difficulties.
• After the Almohad Caliphate’s decline, North African successor states are said to have exported grain to European trading partners, including Italian republics, the Crown of Aragon, and France.

Central Lesson

Climate can affect water supplies, farming, herding, trade, population, and the ability of states to sustain armies and institutions. But it is not a single controlling cause of historical events. Frey Sánchez’s main point is that history is shaped by multiple factors acting together: “history moves in the plural and not in the singular.”
