/jp/ - Otaku Culture

My first time in /jp/... wonder if I'll get flamed?

I need to translate something into coherent Japanese, just not sure how to do it. Here is what I want to say:
"Personally, I think in all countries、cultural events allow people to be able to remember significant historical facts."

I have some vocab:
個人的 personally
万国に (in) all countries
国民　National people　
慣行 customs
できる be able to
大切なの史実をおぼえる remember important historical facts.

Can anyone help me construct the full sentence?
