Answer:
1. Suleiman the Magnificent
2. Religious
3. Reforms
Explanation:
According to historical evidence, the Ottoman and Safavid Empires, with their rulers SULEIMAN THE MAGNIFICIENT and Abbas the Great, helped practice RELIGIOUS tolerance REFORMS.
Superman the Magnificent came to power in 1520, until he died in 1566. During his reign, he was known to be religious tolerant to the Jews and Christians. He performed many socio-political reforms, including taxation, education, and law.
Similarly, Abbas the Great ruled between 1828 to 1629. He also allowed religious tolerance and carried out many reforms, including civil administration and military.
The extension of slavery into the territories split the Democratic party and the Whig party, and opponents of the Kansas-Nebraska Act of 1854 organized the new Republican party. Basically just the unwanted extension of slavery.
