Many English learners see both organization and organisation and wonder which one is correct. The confusion happens because both words have the same meaning, the same pronunciation, and are used in the same way.
The only real difference is the type of English being used.
Some countries prefer organization, while others prefer organisation. Because English is spoken around the world, both spellings appear in books, websites, emails, newspapers, and school materials.
The good news is that neither spelling is wrong. You simply need to know when to use each one.

Simple Origin or Background Explanation
The word comes from the idea of arranging or organizing people, things, or activities in a structured way.
Over time, English developed different spelling styles in different parts of the world.
In the United States, many words were simplified and began using -ize endings. As a result, organization became the standard spelling.
In the United Kingdom and many countries influenced by British English, words often kept the -ise spelling pattern. This led to the spelling organisation.
Even though the spellings changed, the meaning remained exactly the same.
