*Mayflower in Plymouth Harbor* by William Halsall (1882)
**Col. William Brewster III** (1566 – April 10, 1644) was an English official who was a passenger on the *Mayflower* in 1620. He was a religious leader both in Europe and in Plymouth Colony. He was also one of the signers of the Mayflower Compact.

William Brewster III was the son of Capt. William Brewster, Jr. (1533-1622) and Mary Smythe Simkinson (1537-1655), Capt. William Brewster, Jr. was the son of Col. William Brewster, Sr. (1500-1616) and Maud Mann (1506-1619), William III lived in Scrooby, Nottinghamshire, England.

Brewster studied at Peterhouse, Cambridge. Cambridge was a university where many people wanted to change the Church of England. People who agreed with this started different religions. They were called Separatists. In England, Separatists were put into jail.

Brewster worked for a time for William Davison in the Netherlands. Davison went to jail because he was a Separatist. When Davison went to jail, Brewster went back home to Scrooby for a time. He became a postmaster. Brewster began a Separatist church in his house. In 1607, He also went to jail for a short time for doing this in. Brewster and other members of the Church decided to move to Netherlands in 1608. They hoped that would be able to practice their religion there. To leave England without permission was illegal, so they left in secret. In 1609, he was chosen as the leader of the congregation.

In Leiden, Brewster taught English. In 1616 he was a printer and made religious books for sale in England. In 1619, Brewster and Edward Winslow published a religious booklet which disagreed with King James I and the Church of England. The King ordered Brewster's arrest. He was forced to hide. The printing press was taken by the English ambassador and Brewster's partner was arrested. The congregation had already decided to leave Leiden for the New World. While Brewster was in hiding, the other members of the church looked to others such as John Carver and Robert Cushman to make the plans. Brewster escaped and, with the help of Cushman, he and Cushman were able to get aboard the *Mayflower* with their friends. His wife and two of his sons, Love and Wrestling, were also passengers.
