What this topic is asking
Topic 1.2 covers Dar al-Islam - the "house of Islam", the lands where Islam was the dominant faith - between roughly 1200 and 1450. The College Board wants you to explain a central paradox: the Islamic world fragmented politically after the decline of the Abbasid Caliphate, yet it remained unified in religion, learning, and trade, and it acted as a great engine of cultural transfer across Afro-Eurasia.
Political fragmentation: new states replace the Abbasids
The first half of the topic is political change. The unified caliphate of earlier centuries gave way to a patchwork of states.
The College Board's point is that Arab political dominance ended and was replaced by Turkic and other rulers, but Islam as a civilization did not collapse with the caliphate. New Islamic states carried the faith forward and into new regions.
Cultural and religious continuity
Against this political change, the topic stresses powerful continuities.
- Religion. Islam continued to spread, carried less by conquest now than by merchants and by Sufi missionaries whose mystical, adaptable practice won converts across Africa, India, and Southeast Asia.
- Scholarship. Islamic scholars preserved, translated, and advanced learning. They commented on Greek philosophers such as Aristotle, made breakthroughs in mathematics (algebra, trigonometry), medicine, and astronomy, and ran centers of learning that drew students from across the world.
- Trade. Muslim merchants dominated the Indian Ocean and trans-Saharan routes you will study in Unit 2, knitting the Islamic world together commercially even as it splintered politically.
Why this matters for the exam
The College Board loves the continuity-and-change angle here, because Dar al-Islam shows that political and cultural change can move in opposite directions. A state can fall while the civilization it belonged to keeps growing. This is also the setup for Unit 2: the Islamic merchant and scholarly networks are exactly the connective tissue of the Afro-Eurasian trade routes.

A Short Answer Question (SAQ), 3 points, one per bullet.
A. Describe: the Abbasid Caliphate fragmented and new states ruled by Turkic peoples (the Seljuks, later the Mamluks of Egypt) and others took power, ending Arab political dominance.
B. Continuity: Islamic scholars continued to preserve and advance learning in mathematics, medicine, and astronomy, and to translate and comment on Greek works such as those of Aristotle.
C. Influence: Muslim scholars transmitted Greek philosophy, Indian numerals (the basis of the decimal system), and advances in medicine to Christian Europe, partly through Spain and Sicily.
Each bullet must be specific. "Islam was important" earns nothing; "Muslim scholars preserved Aristotle and transmitted Indian numerals" earns the point.

A Long Essay Question (LEQ), scored on the 6-point continuity-and-change rubric.
Thesis (1): "Although Dar al-Islam underwent profound political change as new Turkic and Mamluk states replaced the Abbasids, it remained strikingly continuous in religion, scholarship, and trade, which preserved its cultural unity."
Contextualization (1): situate the period in the long expansion of Islam since the seventh century across Afro-Eurasia.
Evidence (2): political change (Abbasid collapse, Seljuk and Mamluk rule, the Mongol sack of Baghdad in 1258); continuity (the spread of Islam, scholarship, Sufism, and Indian Ocean trade).
Analysis (2): explain HOW religious and commercial continuity outlasted political upheaval, then add complexity by noting that political change carried Islam to new regions, so change drove continuity in its spread.
