Final answer:
The intensified split during 1450-1750 was due to economic, religious, technological, and environmental factors. The Little Ice Age caused migrations for hospitable conditions, while the Reformation deepened religious divides. Technological innovations and trade expansion influenced societal changes and global connectivity.
Step-by-step explanation:
The split that intensified during the 1450-1750 time period can be attributed to a range of factors including economic factors and trade expansion, religious conflicts and wars, technological advancements, and environmental changes. During the 14th century, environmental conditions worsened due to the Little Ice Age, leading to crop failures and food shortages. These conditions forced people to migrate in search of better living conditions. Concurrently, religious conflicts, such as those arising from the Reformation, fueled by the quest for power and spiritual authority, exacerbated divisions. Technological advancements like the printing press and new sailing technologies influenced trade expansion and the spread of ideas, further heightening the split.
Regarding other historical events during this period, the Hundred Years' War between England and France was a series of conflicts over territory and succession, and the weakening of the papacy was due in part to political disputes and the Avignon Papacy. The Little Ice Age was likely caused by a combination of volcanic eruptions and changes in Earth's orbit. The Ottoman Empire experienced decline because of financial difficulties and military failures, and the Seven Years' War was driven by growing rivalries between European powers.
