Two factors that helped to contribute to the scientific revolution in Europe in the mid 1500s were economic expansion and also the translation of ancient Greek texts into the vernacular. Economic development during the Renaissance period led to a new need for engineers, architects, and inventors to help to develop society which led to further development of scientific thought. Additionally with the rediscovery of Ancient Greek texts, thinkers of the time began to further develop empirical ways of thinking based in Aristotelian methods of logic and reasoning. hope it helps :)
The Compromise of 1850 and the Kansas-Nebraska Act also worked to obtain similar results. When the newly founded Republican Party (the first real anti-slavery party) won its first election in 1860 with Abraham Lincoln, the South feared that the government would infringe on its rights and interests, which led to secession, and then the Civil War.
