A High Commission refers to the embassy of a country belonging to the Commonwealth of Nations in another Commonwealth country. The High Commission is headed by a senior diplomat called the High Commissioner.
High Commissions serve as embassies in Commonwealth Nations; embassies have in fact been around for thousands of years. Ancient cities and towns often had ambassadors from other nations.
High Commissions foster healthy relationships between Commonwealth countries. They also help organize programs that promote the culture and heritage of the home country in the host nation.
The High Commission is located in the capital city of the home Commonwealth Nation and serves as an important link connecting the two countries. The High Commission also ensures that the rights and interests of the citizens of the home nation remain protected at all times.
