First of all, let me say, I am an American. I have a hard enough time keeping track of my own country's political history. Second of all, I'm a genre writer, not an historian, so if I decide to use political aspects in my books, it had better be for a good reason.
I've found there are two trains of thought to using politics -- the first, as a decided focus of the main plot. And second, as an added layer to the general background of the setting.
For example:

I used several key figures from Russian history as well as England and although 99% of it is not true, the 1% I did use, worked. Well, it worked for me anyway.

In THE LADY'S FATE, the Marquess of Haverlane and Duke of Cantin, are with Prince George as advisers to get him seated as the Prince Regent. I did not say specifically what they were advising George on, but it got them out of the house.


well as a few particular battles in Spain and Portugal. In THE CAPTAIN'S COINCIDENCE I used the alliance between France and America as a backdrop. Somewhat. (There's so much there I didn't want to get bogged down -- which I did, and then cut it all out.)
In using politics for background, I feel it is better to give a general overall feeling to the plot rather than a history lesson. Unless, as I said previously, you're writing a TRUE HISTORICAL novel. Which I'm not.
Tell me -- How do you feel about using historical information?
