Hello. You have not informed the events to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
If these events are related to a text, you will know the order in which they happen by reading the text. Ideally, you should read the full text, but there are short texts on the internet that can help you find the order of events.
If these events are related to historical periods you can find the order in which they happened by searching, on the internet, the period in which each one was established. You can do this by placing the name of the event on a search platform.
