To ‘establish‘ something can mean to begin or build something. It can also mean to find facts to prove the truth of something.
- The company was established in 2010.

Why is the word ‘was’ used with the verb ‘establish’ in the first example sentence? Do you know? The answer is that it is a passive sentence. In this structure we are not interested in the agent (who or what) established the company.
