What happened on September 16

Head of the Catholic Church from 625 to 638

Pope Honorius I was the bishop of Rome from his consecration on 27 October 625 until his death. He actively supported the Christianisation of the Anglo-Saxons, notably by sending Saint Birinus to convert the West Saxons and bestowing the pallium on the archbishops of York and Canterbury, and worked to persuade the Irish and British churches to adopt the Roman Easter computus. He is most noted for his correspondence concerning Patriarch Sergius I of Constantinople, in which he engaged with the Monoenergism controversy and the associated Monothelite doctrines.

Welsh rebel and pretender (died c. 1416)

Owain ap Gruffudd Fychan or Owain Glyndŵr was a Welsh nobleman and military commander in the late Middle Ages who led a sixteen-year-long Welsh revolt establishing an independent Wales free from English rule. Owain was the last Welshman to claim the title Prince of Wales, and his revolt saw the establishment of a Welsh parliament.

Early settlers in Massachusetts

The Pilgrims, also known as the Pilgrim Fathers, were the English settlers who travelled to North America on the ship Mayflower and established the Plymouth Colony at what now is Plymouth, Massachusetts, United States. John Smith named this territory New Plymouth in 1614, sharing the name of the Pilgrims' final departure port of Plymouth, Devon, England. The Pilgrims' leadership came from religious congregations of Brownists or Separatists who had fled religious persecution in England for the tolerance of 17th-century Holland in the Netherlands.

Jacobite pretender (1688–1766)

James Francis Edward Stuart, also known as the Old Pretender, was the senior House of Stuart claimant to the thrones of England, Ireland and Scotland from 1701 until his death in 1766. The only surviving son of James II of England and his second wife, Mary of Modena, he was Prince of Wales and heir-apparent until his Catholic father was deposed and exiled in the Glorious Revolution of 1688. His Protestant half-sister Mary II and her husband William III and II became co-monarchs.
