Argentine tea culture emigrated to Argentina seeking cultural freedom during a time in the 19th century when the Welsh language was suppressed in Great Britain. The Welsh tea customs are similar to those practised throughout Great Britain and Ireland, with tea being served at approximately 4:00 p.m., the tea beverage being mixed with milk and sugar and consumed alongside cakes and pastries. A combination of British tea culture and Argentine cuisine can be found in some establishments in Buenos Aires, where tea is served in the late afternoon following the British custom. Traditional British tea varieties such as Earl Grey are served with
Prime minister and in British colonial territories as they developed self-government. In some places alternative titles such as "premier", "chief minister", "first minister of state", "president of the council" or "chancellor" were adopted, but the essentials of the office were the same. By the late 20th century, the majority of the world's countries had a prime minister or equivalent minister, holding office under either a constitutional monarchy or a ceremonial president. The main exceptions to this system have been the United States and the presidential republics in Latin America modelled on the U.S. system, in which the president directly exercises executive authority.
