How can the tudor period be considered a turning point in british history

A lot of famous and infamous monarchs have come from the Tudors.
The Tudor dynasty was a turning point from the beginning because its first monarch, Henry VII, became the monarch at the end of a series of battles now known as the War of the Roses.

Later on, the well-known monarchs Mary I ("Blood y Mary") and Elizabeth I, both members of the Tudor dynasty, came to throne, performing many history-changing actions.
