PROBLEM: Paragraph- Sent 1: The Crusaders established a feudal Christian state with Godfrey at its head.
Sent 2: They built many impressive churches during the term of the first Latin Kingdom of Jerusalem, but in 1187 they were driven out by Muslim forces under the great warrior Saladin.
Sent 3: During the Sixth Crusade (1228 1229), the Holy Roman Emperor Frederick II managed to secure Jerusalem for the Christians by negotiation.
Sent 4: The Christians, however, could not hold the city.
Sent 5: After they lost Jerusalem, a Mongol invasion swept through, and in 1244 the Mameluke dynasty of Egypt took control, ruling Jerusalem for the next 250 years.
Sent 6: The city struggled to rebuild from Crusader wars and invasions.
Sent 7: Much of the best Islamic architecture in the city was constructed in the Mameluke era, but the past thousand years had taken their toll: Jerusalem was unable to regain the prosperity it had enjoyed in earlier times.
Sent 8: In the early 16th century, the Ottoman Turkish Empire was advancing through the Middle East.
Sent 9: Jerusalem fell to the Ottomans in 1517, remaining under their control for 400 years.
Sent 10: Suleiman the Magnificent rebuilt the walls and gates in the form they retain to this day.
Sent 11: Fountains, inns, religious schools, and barracks were constructed.
Sent 12: But when Suleiman died, his empire, including Jerusalem, began a long period of decline.
Sent 13: The Holy City remained a backwater until the 19th century, when renewed interest among Christian pilgrims made it the destination of thousands of travelers each year.
Sent 14: 19th-Century Aspirations At the same time, many Jews sought religious freedom and fulfillment by moving to Palestine (as the Holy Land was traditionally called) and especially to Jerusalem.
Sent 15: In the 1890s, Theodor Herzl (18601904) worked to organize a movement, Zionism, to create a Jewish state.
Sent 16: Chaim Weizmann (18741952), a scientist born in Russia but later a British subject, did much to put Herzl's hopes into practice.
Sent 17: Weizmann was an important figure in the negotiations with the British government that led to the Balfour Declaration of 1917, supporting the idea of a Jewish "national home" in Palestine that also respected the rights of existing non-Jewish people already living there.
Sent 18: The problem was that British strategists, who were fighting the Ottoman Turks in 1917, had secretly promised the lands to their World War I Arab allies.
Question: Before the Mongols, who was in control of Jerusalem?.
