I did British monarchs last year while on a history kick, (which I'm still on). Pro-tip: watch films, television shows and plays featuring said monarchs, as they include salient contemporary historical events. For example, Nigel Hawthorne was the mad George. Hugh Laurie was his son, the Prince Regent, a contemporary of the Duke of Wellington (Stephen Fry), which places him temporally alongside the Napoleonic wars. Colin Firth was Queen Elizableth II's stuttering dad in The King's Speech. His brother was Mike from Neighbours (or the bad guy from Iron Man 3 if you're under 30) and their dad was Dumbledore.
(It turns out that royal history has plenty of independently interesting features, because it contains a lot of murders and wars and speculation about parentage. Contemporary introductions to historiography emphasise the movement away from history as the deeds of powerful men exercising their will through war and conquest, but the kings and wars are a lot more memorable and easier to place in time than the ephemeral stuff like trade routes and adoption of crops.)
