The Tudors ruled England from 1485 until 1603 which is not that long, really, just 118 years. But they were immensely consequential.
Henry VI took England out of the War of the Roses and brought a level of stability back.
His son Henry became Henry VIII when his brother died before he could assume the crown.
Henry VIII longed for a male heir and burned through six wives looking for one.
He first married his brother’s Catherine of Aragon but had it annulled after she didn't give birth to a boy (she did have one son but he died in infancy).
