If you post the two definitions here, and technology us which parts of these definitions you do not understand, then we shall explain them to you. We would like to help you learn how to use a dictionary.

A "pilgrim," lower-case p, is someone who makes a religious journey to a holy place. In the United States, "the Pilgrims" refers to a group of Puritans who traveled to North America to found one of the earliest colonies. The Puritans were a group of English Protestants in the 1500s and 1600s who followed the doctrine of John Calvin, which they believed to be "purer" than that of the Church of England. At that time, the Church of England was the "established church." Other beliefs were not actually prohibited, but, for example, to hold state office in England you had to be a member of the Church of England. The Pilgrims were a group of Puritans who felt oppressed, and left England to pursue their religious beliefs, traveling first to Leiden, Holland, and then to North America, where they formed a new colony in Massachusetts Bay. This turned out to be an important event in U.S. history. One of the group, who wrote a history of the colony, used the word "pilgrims" to describe their decision to make a long journey and found a new colony rather than returning to England. The voyage of the Pilgrims in the ship named the "Mayflower," its landing in Plymouth in 1620--supposedly setting foot on a specific stone named Plymouth Rock--has acquired a mythic intensity, with families who "came over on the Mayflower" feeling entitled to a special status. In the early history of Massachusetts, Boston, Salem, and other settlements were ruled by Puritans in what has been called a "theocracy." Despite having come in pursuit of their own religious liberty, they were harshly intolerant of others, and at least one Quaker, Mary Dyer, was hanged in Boston for her religion. The Puritans were very strict--among other things they prohibited the celebration of Christmas on the grounds that it wasn't authentically Christian but had pagan roots. The word "puritanical" can mean "being unreasonably strict about sexual and other morals."
