How can I get temperature data for each Country (Annual)

Question

I need maximum and minimum temperature data of each countries annually.

I searched a lot but could not find the values.

Could you give links if it is possible?

This is very coarse data from the worldbank. It shows historical average temperature per country:

Using their Climate API you can get slightly more detailed information and by per year. I believe they have data going back to 1961.

Berkeley Earth provides aggregated data on world temperature averages going back to 1750, and country/city data going back to 1960.

Then there is NASA's global temperatures database collected from 500 stations, some going back to 1720. I haven't used this tool yet, so I'm not sure how to navigate it.

Then there is NOAA. It's datasets, while primarily US, includes datasets for data collecting from weather stations around the world:
