Despite my father not "getting" history at all, nor seeing the point in it, I was lucky to have a very good teacher, so was not discouraged at school.
We never had a text book. She just stood in front of the class and told us everything. We took notes and had to write them up in our exercise books, and every few weeks we were given a topic to write an essay on. The help she gave us learning how to take notes, summarise, and write those essays was invaluable for all other subjects.
I just think it a shame that the O level syllabus constrained all our lessons and we had to concentrate on the Tudors. I would have loved to know more about the Stuarts who followed them. The Civil War, and Scottish and Irish history were just not on the menu.
Since moving to Europe, I have found that everywhere I go, there's a new strand of history to learn about. Trying to connect them up is quite an exercise! As DH was a Latin teacher, we usually visit Roman digs, but then you go to the big Cathedral towns and discover wonderful castles and churches built by the Hapsburgs, the Wittelsbachs, and French and Prussian dynasties. The Reformation plays a huge part over most of Europe (fortunately, of course, that was a huge factor in Tudor times, so I can connect that back to what I learned at school). Then in The North, where the Romans didn't get to, it's a whole new world of Slavic and Scandinavian history. The buildings are radically different due to the predominantly Protestant philosophy and the different materials available.
I love trivia and quizzes, and to help with connecting the information I like to know the dates of things. Nowadays dates seem to be given less importance, but I can't understand how people can learn about the past without them.
The history section of Radio 4's "In Our Time" is fascinating as it really goes into detail.
I hadn't really thought about it all being killing, rape and pillage, especially often in the name of religion. I just thought "different times". But, as previous posters have said, humanity doesn't seem to have learnt anything. There is still a lot of cruelty, corruption, exploitation and greed in the world. And most of it is in charge of running countries, religious movements and organisations in all sectors.
