1710-1729 Succession Issues in England and Spain

This twenty year period covers the reign of Queen Anne who died in 1714 and was replaced by George I, the Hanoverian son of Sophia (the niece of Charles I) who, in turn, died in 1727 and was succeeded by his son George II. In this period there was constant warfare in the world, as usual.

This twenty year period covers the 1702–1713 Queen Anne's War in North America, which was part of the War of Spanish Succession. Then came the 1711 Tuscarora War, the 1712–1714 First Fox War, the 1714–1718 Turko-Venetian War, the 1715 Yamasee War, the 1715–1716 Jacobite Rising, the 1715–1717 Polish revolt against King Augustus II, the 1716–1718 Austro-Turkish War, the 1718–1720 War of the Quadruple Alliance, the 1722 Dummer's War in Maine, the 1722–1723 Russo-Persian War, the 1722–1727 Turco-Persian War, the 1727–1729 Spanish war between England and France, and the 1728–1737 Second Fox War.

There were no inventions, discoveries or great ideas during this 20 year period which was totally overshadowed by succession issues in both England and Spain. 

The Jacobites had good reason to fight for the restoration of James II after Queen Anne died. Nobody liked a German who could not even speak English becoming King of England -- but George I was Protestant, not Catholic like James II and that's all that mattered.
