What were the three main causes of death for the pilrims?

The three main causes of death for the Pilgrims during their early years in America were harsh weather conditions, malnutrition, and disease. The brutal winter of 1620-1621 led to inadequate shelter and exposure to the elements. Many Pilgrims also suffered from scurvy and other illnesses due to a lack of proper food and nutrition, compounded by the stress of their new environment. These factors collectively resulted in a high mortality rate during their first year.
