I think it was still communism
A reason for French exploration and colonization in North America is that A)They wanted to find a northwest sea passage to get to Asia. This can be seen with Jacques Cartier who claimed Canada for France and was the first European to describe and map the Gulf of Saint Lawrence and the shores of the Saint Lawrence River. He made a voyage to the New World in hopes of discovering islands where big quantities of gold were supposed to be located.
This is certainly a sensible topic and I'm afraid there's no easy answer as it's very dependant on context.
The criteria for rejecting or accepting certain immigrants will vary depending on the cultural and political relationship between the country where each immigrant comes from and the country they intend to relocate to.
Every nation should aspire to generate conditions of tolerance in which ethnic or racial differences don't represent a threat to the safety of their communities. To achieve this, it would require governments a sustained effort to educate its people in favor of diversity and apply policies that encourage freedom and protect civil liberties. <u>However, </u>t<u>his is a long and arduous process that history has shown sometimes may take several centuries</u>.
In many cases, the tensions between different ethnicities and cultural backgrounds are so high at the present time, that there's no other way to ensure safety than limiting specific types of immigration in certain regions. That is why to me, it is legitimate for a country to take nationality, race and religion into account when deciding who they let in, as long as the government keeps moving towards tolerance in the long-run.
Hope this helps!
The major thing that they supported was creating a worldwide revolution and spreading communist ideology. They wanted for workers of the world to unite and build a communist worldwide state based around the proletariat and their goals. The proletariat were the working class since they were the ones who contributed the society the most so it was natural according to them that they should be in charge.
