What was the aim of the chartist movement, which organized in britain in the 1830s?

The aim was to gain political influence for the working class.

A key example of this would be the People's Charter of 1838, which was written by the London Working Men's Association (LWMA). It included 6 demands:

1. Equal representation in parliament

2. Voting through secret ballots

3. Payment for MPs (members of parliament)

4. Universal suffrage

5. No more property qualification (to vote)

6. Annual parliamentary elections instead of every 5 years.
