1086
Domesday Book completed
At Salisbury, William the Conqueror received the completed survey of English land and resources, compiled by royal commissioners in a single year. Down to the last ox and pig, the Domesday Book recorded the Conqueror's kingdom more thoroughly than any government had surveyed its subjects in a thousand years. No comparable census of an entire nation would be undertaken again in Europe until the modern era.
Almoravids Cross the Strait and Enter al-Andalus
Following their victory at Sagrajas, Yusuf ibn Tashfin's Almoravid forces remained in Iberia, gradually absorbing the squabbling taifa kingdoms that had invited them as saviors. One by one, the petty Muslim courts of Seville, Granada, and Badajoz discovered that their Saharan allies had no intention of going home. The Almoravids were not rescuers - they were conquerors with better theology and longer memories than the taifa kings they replaced.
Song Dynasty Water-Powered Textile Mills Proliferate
Water-powered spinning wheels and silk-reeling machines spread through the Yangtze Delta, transforming textile production from cottage craft into something approaching mechanized industry. The technology used water wheels to drive multiple spindles simultaneously, multiplying output by factors that astonished visiting merchants. Song China's textile exports - silk, cotton, hemp - flowed outward through Guangzhou and Quanzhou to markets stretching from Japan to the Persian Gulf.
Battle of Sagrajas
Yusuf ibn Tashfin's Almoravid army, summoned by the taifa kings of al-Andalus to halt Alfonso VI's advance, crushed the Christian forces near Badajoz. Alfonso escaped with five hundred horsemen out of sixty thousand. The Almoravid intervention revitalized Muslim Iberia and stalled the Reconquista for decades. The thunderous sound of Almoravid war drums, never before heard in Spain, terrorized the Christian cavalry into breaking formation.
