Help tranlate into japanese?

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?

that is overly complex and nothing like how a native would say it
