Founded in 1357, Hoorn rapidly grew to become a major harbour town. During Holland's 'Golden Age' (or 'Golden Century'), Hoorn was an important home base for the Dutch East India Company (VOC) and a very prosperous centre of trade. The Hoorn fleet plied the seven seas and returned laden with precious commodities. Exotic spices such as pepper, nutmeg, cloves, and mace were sold at vast profits. With their skill in trade and seafaring, sons of Hoorn established the town's name far and wide. Jan Pieterszoon Coen (1587-1629) is famous for his violent raids in Dutch Indies (now Indonesia), where he "founded" the city of Batavia in 1619 (now Jakarta). He has a big statue on the Rode Steen square in the center of Hoorn.
In 1618 Willem Ysbrandtsz Bontekoe (1587-1657) undertook his first and only voyage for the VOC. His story of his travel and hardship found its way into the history books when he published his adventures in 1646 under the title Journael ofte gedenckwaerdige beschrijvinge van de Oost-Indische reyse van Willem Ysbrantsz. Bontekoe van Hoorn, begrijpende veel wonderlijcke en gevaerlijcke saecken hem daer in wedervaren. In 1616, the explorer Willem Corneliszoon Schouten braved furious storms as he rounded the southernmost tip of South America. He named it Kaap Hoorn (Cape Horn) in honour of his hometown.
Hoorn's fortunes declined somewhat in the eighteenth century. The prosperous trading port became little more than a sleepy fishing village on the Zuiderzee. Following the Napoleonic occupation, there was a period during which the town gradually turned its back on the sea. It developed to become the market for the entire West Frisian agricultural region. Stallholders and shopkeepers devoted themselves to trading in dairy produce and seeds. When the railway and metalled roads came to Hoorn in the late nineteenth century, the town rapidly took its rightful place as a conveniently located and readily accessible centre in the network of towns and villages which make up the province of Noord-Holland. In 1932, the Afsluitdijk, or Great Enclosing Dyke, was completed and Hoorn was no longer a seaport.
The years after the Second World War saw a period of renewed growth. At the centre of a flourishing horticultural region, Hoorn developed an extremely varied economy. During the 1960s, Hoorn was designated an 'overflow' city to relieve pressure on the overcrowded Randstad region. Thousands of people swapped their cramped little apartments in Amsterdam for a family house with garden in one of Hoorn's modern new developments.
On the 26th of March 2007, Hoorn will celebrate 650 years as a city. In 1357 Hoorn was awarded city rights by the Count of Holland after a lump sum payment of 1500 "schilden" to the Count.
Hoorn is directly linked with the vanished United States Zwaanendael Colony that was massacred in a dispute with Nanticoke Indians and the town of Lewes, Delaware that was re-established on its site. A Zwaanendael Museum exists in present day Lewes and is a replica of the town hall of the city of Hoorn.
