The story
The settlement spread in the area of the present Seinäjoki during the first half of the 16th century. During the 1550s, there is said to have been three houses in Seinäjoki: the houses of Marttila, Jouppi and Uppa. The house of Jouppila, which separated from the house of Jouppi, was established during the same century. All of the houses were located on the shore of the river.
Seinäjoki belonged to the church parish of Ilmajoki like Kurikka, Kauhajoki, Jalasjärvi and Alavus. However, in the 18th century the roads from Seinäjoki to the Church of Ilmajoki were generally in poor condition. Therefore, the inhabitants of Seinäjoki and the neighbouring Nurmo built a new chapel together in 1725, which in 1765 led to the formation of the chapel town of Nurmo. Seinäjoki, which was called Alaseinäjoki since the Greater Wrath, became a part of the chapel town. The chapel parish of Peräseinäjoki was founded in 1798, and the village of Alaseinäjoki began to be called Seinäjoki again. The very same year, the Östermyra steel mill was founded on the shore of the Seinäjoki river.
In the 1850s, actions were taken to separate Seinäjoki from the church parish of Nurmo. Ilmajoki wanted to connect Seinäjoki back to its own parish. In spite of strong objections from the inhabitants of Nurmo, the Senate of Finland accepted the petition from the inhabitants of Seinäjoki in 1863, to form a chapel congregation of their own. Seinäjoki got an independent local government in 1868. In 1900, Seinäjoki became an independent municipality.
Seinäjoki has grown around a few important railroad crossings. The Tampere–Vaasa railway, which passes through Seinäjoki, was inaugurated in 1883. The track, along with the Kokkola track that was opened for rail service in 1885, and the Kristinestad track which had been completed in 1913, raised Seinäjoki as an important railway crossing section in Finland. In the early 1970s, a direct railway between Tampere and Seinäjoki was opened, and the services of Seinäjoki improved further.
After the Winter War and Continuation War, some refugees from Jaakkima and Lumivaara were resettled to Seinäjoki.
