Moernity is a term that refers to the modern era. It is distinct from modernism, which, in different contexts, refers to cultural and intellectual movements of the period c. 1630-1940. The term "modern" can refer to many different things. Colloquially, it can refer in a general manner to the 20th century. For historians, the Early Modern Period refers to the period roughly from 1500 to 1800, with the Modern era beginning sometime during the 18th century. In this schema, industrialization during the 19th century marks the first phase of modernity, while the 20th century marks the second. Some schools of thought hold that modernity ended in the late 20th century, replaced by post-modernism, while others would extend modernity to cover the developments denoted by post-modernism and into the present.
