Here's why:
* William Bradford did write a journal: It's called "Of Plimoth Plantation", and it's a detailed account of the Pilgrims' journey and early years in Plymouth Colony.
* He documented challenges: Bradford was very honest about the hardships the colonists faced – harsh winters, food shortages, conflict with Native Americans, and the loss of many settlers.
* He wanted to encourage others: While not the primary purpose, Bradford's journal was used later to demonstrate the success of the colony and encourage further settlement.
However, it's important to note:
* Bradford's writing wasn't intended for immediate publication: It was a personal record meant for the colony's archives. It wasn't published until much later.
* Bradford's perspective is biased: His journal highlights the Pilgrims' triumphs and minimizes their own failings or conflicts with Native Americans.
Therefore, while Bradford's journal was a valuable historical document and did encourage future settlement to some degree, it's not entirely accurate to say its primary purpose was to encourage people to come to the New World.
