The dance wasn't successfully introduced in Europe for years. Few Tango enthusiasts tried to popularize Tango in Paris, but European society wasn't ready for a dance as exotic as Tango.
Tango's breakthrough happened on the dance floor on French Riviera. From then on, Tango gained popularity in Paris and later in the rest of the world.
Today, International Tango is characterized by snappy movements, fast, dynamic actions switching to superb stillness. It's a very popular and attractive dance.
