1650 - 1652 CE
The first English coffee house opens at Oxford University, and several more soon open in London

The first English coffee house opens at Oxford University. In the following years, more coffee houses open in London, and are known as "penny universities". A leisured class of Renaissance men had brought the Turkish social practice of coffee drinking to Western Europe. Called "penny universities” because that was the price of a cup of coffee, the shops became the “in” places for men from all walks of life to gather, engage in polite conversation and sober debate on matters of politics, science, literature, commerce and religion.
