How did the pilgrims condition change from their first winter to the time of the first thanksgiving?

The Pilgrims faced severe hardships during their first winter in 1620, with many succumbing to illness and starvation, leaving only about half of the original settlers alive by spring. However, by the time of the first Thanksgiving in 1621, their condition improved significantly due to a successful harvest and assistance from the Wampanoag people, who taught them vital agricultural practices. This newfound stability allowed them to celebrate their harvest with a feast, marking a pivotal moment in their settlement experience.
