Trzemeszno [t'mn?] (German: Tremessen) is a town in central Poland belonging to the group of the oldest settlements in the region. The town's name derives from an Old Polish word "Trzemcha" meaning the flower of the "Bird's Cherry" plant, which once grew in the vicinity. It is situated in Greater Poland Voivodeship; previously it was in Bydgoszcz Voivodeship (1975-1998).
Around the 10th century, a kind of defensive settlement was created here. It soon changed its function into a market settlement. It was significant that the town lay on the trade route joining Greater Poland with northern Masovia and Pomerelia.
In the 12th century, Trzemeszno became a property of the monastery of Canons regular of St. Augustine. The monks were brought there by prince Boles?aw III Wrymouth. Trzemeszno received its town rights before 1382.
From the second half of the 17th century, there began a decline of the town and region caused by wars (Swedish invasions) and plagues. In 1766, there were only 15 houses left in Trzemeszno. However, soon the town started to develop rapidly. An important period in town's history is due to the activity of Micha? Ko?ciesza Kosmowski, who was the monastery abbot (1761-1804). He founded the "New Town" - a suburb, where cloth makers were settled, and St. Michael's suburb for other craftsmen. Kosmowski founded also several buildings of public services: "Collegium Tremesnensis" a secondary school, hospital and a new brewery. The Polish patriot, Jan Kili?ski, was born here in 1760. In 1791, there were 144 buildings in the town and almost 1000 people lived there. The main activities of the residents were connected to crafts, trade and framing. The enterprise, which took up artistic challenges, was rebuilding and changing into baroque style of the monastery church. The work was finished in 1791 when the church was consecrated.
In 1793, due to the second partition of Poland, Trzemeszno became a part of Prussia and after Napoleon I, in 1815 it was incorporated into the Grand Duchy of Posen. In 1849, Trzemeszno was renamed "Tremessen" and belonged to Kreis Mogilno of the Prussian Province of Posen. It was registered within Standesamt Tremessen.
In 1836 the government secularized the monastery.
In 1848, Trzemeszno became one of the main centers of national liberation movement in Greater Poland. The town's residents (including many students) were also involved in the January Uprising (1863). Trzemeszno's secondary school has traditions of participating in national liberation fights. In 1844, a secret society of students called "Sarmatia" formed and from 1861 the National Society "Zan" was active.
In 1865, a Loan Bank (Kasa Po?yczkowa) and in 1874 an Industrial Society (Towarzystwo Przemys?owe) were founded in Trzemeszno. The later was significant for culture and education. Around 1880, a branch of Towarzystwo Czytelni Ludowych ("Society of Public Reading Rooms") and in 1894 the Gymnastic Society Sokó? were founded.
Opening a railway line in 1872 joining Trzemeszno with Pozna?, Toru? and Inowroc?aw had contributed to the town's development.
At the end of World War I, in the early days of the Greater Poland Uprising, the Polish residents of Trzemeszno took control of their town on December 29, 1918; the town become a part of newly reconstituted Poland in the following months. The first years in free Poland were good for developing trade and crafts. However the situation was complicated by inflation, unemployment and economical crisis. Despite these problems, cultural and educational life flourished. Many events were organized by local societies and organizations. There was a cinema, and in 1937 the local weekly newspaper "Kosynier" began to be published. Secondary school played an important role in local culture.
In September 1939 the residents of Trzemeszno faced Nazi invasion. During the Nazi occupation, the town's name was changed to "Tremessen" again. Schools, libraries and the church were closed. However, terrorized residents did not remain passive. There was a secret military organization and a secret scout organization (Szare Szeregi).
After 1945, residents of Trzemeszno faced many difficult tasks. "Citizen Committees" were responsible for restoring closed enterprises and community services. The greatest challenge was restoration of the basilica church and secondary school which had been burned down by retreating Nazi troops.
Rapid development of Trzemeszno took place in the 1960s and 1970s. The largest enterprise, employing over 1000 people, was Pomorskie Zak?ady Materia?ów Izolacyjnych "Izopol" (factory producing insulation materials). "Izopol" played an important role as a financial supporter and developer of the town.
In 1999, due to the administrative reform of Poland, Trzemeszno became a part of the Gniezno powiat and the Greater Poland Voivodeship.
