History
Ancient history
It is estimated that the first people reached the area around what is today Södertälje during the Stone Age, about 4000 BC. They formed settlements around 3000 BC, when the peasant culture is believed to have reached the area. Around 1500 to 400 BC, the strait between Lake Mälaren and the Baltic Sea narrowed due to the post-glacial rebound. Thereafter boats had to be towed over the sand ridge, which created job opportunities. Trade and service emerged.
Ansgar passed through Södertälje on his voyages to Birka in his efforts to Christianize Sweden in 829. Södertälje was first mentioned in historical sources in 1070, when Adam of Bremen mentioned the town in a description of the road between Skara and Birka in his work . However, the area was inhabited long before then. Södertälje received city privileges in the 1300s.
The castle Telge Hus was built at Slottsholmen during the 1300s. From here, Telgehus county was administered between the years 1318 and 1527. The county included Öknebo, Hölebo and parts of Svartlösa districts. Archaeological excavations have shown that the castle was surrounded by a moat. It is still partially visible on Slottsholmen's northwestern shore.
Originally, the city was simply called Tälje (several spellings are known; including Telge, Talje, and Tælga). In 1622, the prefix 'south' was added to distinguish from the then recently founded town of Norrtälje, located 110 km northeast of the city. Statistics Sweden started using the modern spelling in 1900.
The city first used St. Olof in its coat of arms. At the beginning of the 17th century, he was replaced by Ragnhild of Tälje (). After her pilgrimages to Rome and Jerusalem, her relics are said to have been buried in Södertälje.
Duke Charles (subsequently became King Charles) actively invested in Södertälje as a commercial and maritime city during his time as Duke of Södermanland, which contributed to growth. A port was built just south of the city. It was not until the 1740s that the city began with industrial manufacturing in addition to shipping and trade.
1800s to 1950
Södertälje already had a port, but during the 19th century it became necessary to extend it to be able to receive larger vessels. In 1819 the Södertälje Canal was inaugurated after 13 years of construction. Just over forty years later, in 1860, rail traffic between Södertälje and Stockholm commenced. The Western Main Line for trains between the east and west coast of Sweden opened in 1862, with a station in the city.
Around this time Södertälje became known as a seaside resort for Stockholmers. In 1849 the Södertälje Bathing Facilities in Badparken park was opened, with both a cold bath facility and a hot bath house. The bathhouses and the Societetshus venue have been demolished, but the Bath hotel at Järnagatan street, Strandhotellet hotel, Stadsparken park and Villa Bellevue still remain from the resort era, which lasted for almost a hundred years until 1945.
The tradition of selling the local pretzels, , is several hundred years old. They had their heyday during the resort era, i.e. around the beginning of the 19th century onwards. They were typically sold by older women, often referred to as (English: Pretzel ladies). The pretzels were primarily sold to tourists, especially at the city's railway stations. The sale of pretzels, among other aspects of the resort town, was described in the magazine (English: Swedish Family Journal) in 1881.
By the 1900s, Södertälje's population had grown to over 8,000 people. Around the turn of the century several large factories were established in the city: Svenska Centrifug AB (1896), AB Södertelge Verkstäder (1897), Baltic (1906), Aktiebolaget Astra Apotekarnes Kemiska Fabriker (Astra) (1913), Tobaksmonopolet (1915) och Wedaverken (1917). Perhaps most interesting is the formation of VABIS, Vagnfabriks-Aktiebolaget in Södertelge (1891). In 1911 it merged with Scania and formed Scania-Vabis. Nowadays, however, the company only uses the name Scania AB.
