TIMELINE-3

May 1529
DISTINGUISHING CHARACTERISTICS
Sultan Süleyman and his army do not experience heavy rains on their march to Vienna, and consequently are not forced to leave most of their siege weapons behind due to the difficulty of dragging them through mud. They reach Vienna in mid September and besiege the city. The Ottomans triumph, conquering Vienna. After a few months of amassing forces and warding off attacks from the Germans, the Ottomans begin conquering Europe, taking over most of the Holy Roman Empire by 1552, as well as capturing territory in Arabia (including Mecca) upon an onslaught of Safavids in 1535.
Süleyman I is killed in 1554, and the Ottoman Empire begins to break up as Süleyman's son, Selim, battles with his older and illegitimate brother. The French, along with some rebellious Germans, recapture a large portion of the Holy Roman Empire. One of Süleyman's nephews, Mehmet, kills both brothers and takes control of the Ottoman Empire in 1558, but one of Süleyman's generals, Hamza, breaks away from the Ottoman Empire, taking a large portion of the Ottoman army with him as well as all Ottoman territory besides captured land in the former Holy Roman Empire; Transylvania, Moldavia, and Wallachia; and Venice. Hamza captures Baghdad and makes further incursions into Safavid Persia. Mehmet sweeps southwards into Italy, capturing Rome (and with it, the Papal States) in 1562. He then moves on into France, taking Paris in 1563 and sweeping down to conquer the rest of France by 1570. Meanwhile, Hamza amasses a new army in Morocco and his forces recapture Granada in 1561, moving inland to conquer much of Castile and Portugal. In 1564, Hamza's original army and fleet make attacks on Sicilian territory, capturing it between 1564 and 1566. His forces based in Castile conquer Madrid and the remainder of Portugal in 1565. By 1572, Spain is entirely under Muslim rule.
Hamza dies in 1571 and is succeeded by Salëman. Mehmet and Salëman's territories meet in 1572 and they begin fighting each other. Mehmet, being a far more experienced general, pushes into Spain, taking what was formerly Navarre and Aragon, as well as taking all of mainland Italy, leaving Sicily to Salëman.
Only the Scandinavian countries remain Christian and unconqured, and the Reformation continues in those countries while it grinds to a halt in countries under threat from the Ottomans. The Renaissance is also ended before it can really begin and mosques are erected throughout Europe; churches being converted into mosques or being torn down.
Over time, the two Ottoman Empires break up into five smaller empires. The Americas are first settled by Europeans in 1736 and the Islamic Renaissance begins in the mid 1800s. By 1980, the whole of North and South America have been settled by European, African, Asian, and Middle Eastern peoples with the Japanese occupying what is now British Columbia and Washington. The rest becomes predominantly Muslim, though a new religion, Selism, arises in South America, focusing around the worship of Nock, a benevolent deity believed to be in constant conflict with the Islamic God.
(Sorry, I have way too many details) ;)
FINAL NOTES
In this timeline, the world is completely different because it didn't rain a lot in 1529 and the Siege of Vienna succeeded. Had it rained, none of this would have happened, so blame the lack of rain for the whole thing.
EDIT: Alternately called Ottimeline.
