Which of the following factors contributed to the collapse of many Bronze Age empires around 1200 BCE?

The collapse of many Bronze Age empires around 1200 BCE was significantly influenced by climate shifts and the arrival of the Sea Peoples. During this period, there is evidence suggesting that a series of environmental changes led to droughts and reduced agricultural productivity. Such climate instability would have strained resources, making it difficult for these empires to sustain their populations and maintain their economies.

Simultaneously, the Sea Peoples, a coalition of naval raiders from various regions, launched attacks on several coastal cities and trade routes throughout the Eastern Mediterranean. Their invasions disrupted trade networks and undermined the political and military structures of established empires. As these empires faced both internal stress from resource scarcity and external pressures from invasions, many were unable to survive, leading to widespread collapse.

The other factors mentioned, such as Roman invasions or internal revolts, did not contribute to this particular collapse around 1200 BCE. The Romans rose to power much later in history, and while internal unrest was indeed a common issue for many empires, the immediate triggers for the Bronze Age collapse were more closely linked to environmental factors and external invasions.
