The right that was named by the supreme court as part of the freedoms of assembly and petitions was the Right of Association.
This right expresses the individual's right of joining and leaving groups voluntarily, to take individual actions to follow the interests of members in a collective action and to accept or reject memberships.
The Freedom of Association gives a person the right to join other people to promote, express, pursue interests that are common to them.
Moreover, this right is guaranteed by all legal systems. For example, article 11 of the European Convention on Human Rights or the United States Bill of Rights.

Imperialism is a political and military philosophy in which one country or government seeks to conquer other countries and societies and bring them under the control or influence of the invading country.
Imperialism is often associated with the economic theory of mercantilism, in which the conquering country (known as the metropole) becomes the center of manufacturing and production while the conquered countries (the colonies) become the suppliers of raw natural goods. Under a mercantilist system, the point of having colonies is to enrich the metropole.
Imperialism takes a number of forms. There's settler colonialism, where a metropole established colonies to gather raw goods or resources (New York and Jamestown are examples). There's religious imperialism, in which a country invades other countries for the purposes of spreading a religion (Spain was infamous for this) or establishes religious communities abroad (as in Massachusetts Bay).
Imperialism has also existed for ages and ages. The Romans are one famous example, but virtually every country in Western Europe (France, Britain, Spain, Portugal, Germany, Belgium, etc) had an empire at one point. But so did the Japanese, the Russians, the Zulus, and the Comanches.
