Here is a question about this article: The Frankish kingdom in northern Gaul split into kingdoms called Austrasia, Neustria, and Burgundy during the 6th and 7th centuries, all of them ruled by the Merovingian dynasty, who were descended from Clovis. The 7th century was a tumultuous period of wars between Austrasia and Neustria. Such warfare was exploited by Pippin (d. 640), the Mayor of the Palace for Austrasia who became the power behind the Austrasian throne. Later members of his family inherited the office, acting as advisers and regents. One of his descendants, Charles Martel (d. 741), won the Battle of Poitiers in 732, halting the advance of Muslim armies across the Pyrenees.[K] Great Britain was divided into small states dominated by the kingdoms of Northumbria, Mercia, Wessex, and East Anglia, which were descended from the Anglo-Saxon invaders. Smaller kingdoms in present-day Wales and Scotland were still under the control of the native Britons and Picts. Ireland was divided into even smaller political units, usually known as tribal kingdoms, under the control of kings. There were perhaps as many as 150 local kings in Ireland, of varying importance.
What is the answer to this question: What was the title of Pippin?

So... Mayor of the Palace

Here is a question about this article: Following the earthquake, Joseph I gave his Prime Minister even more power, and Sebastiao de Melo became a powerful, progressive dictator. As his power grew, his enemies increased in number, and bitter disputes with the high nobility became frequent. In 1758 Joseph I was wounded in an attempted assassination. The Tavora family and the Duke of Aveiro were implicated and executed after a quick trial. The Jesuits were expelled from the country and their assets confiscated by the crown. Sebastiao de Melo prosecuted every person involved, even women and children. This was the final stroke that broke the power of the aristocracy. Joseph I made his loyal minister Count of Oeiras in 1759.

Sebastiao de Melo prosecuted every person involved, even women and children
