Aadorf is a municipality in the district of Münchwilen in the canton of Thurgau in Switzerland. In 1996 Ettenhausen, Guntershausen bei Aadorf and Wittenwil merged into Aadorf.
Aadorf is first mentioned in 886 as Ahadorf. The oldest record of Tänikon, now part of Ettenhausen, dates to 789 as Tanninchova. Tänikon is also the site of the Tänikon monastery, founded in the 13th century. Aawangen is first mentioned in 844 as Oninwanc. Ettenhausen is first mentioned in 1278 as Oetenhuse. Guntershausen bei Aadorf is first mentioned in 1282 as Gundolthuser tal. On 6 April 1358 the brothers Herman and Beringer von Landenberg and Hermann von Landenberg donated the church of Aadorf to the Rüti Abbey.
The territory of the municipality was enlarged in 1996, when it absorbed the neighboring municipalities of Aawangen, Ettenhausen, Guntershausen bei Aadorf and Wittenwil. As of 2008, it was the canton's seventh largest municipality.
Graves from the Hallstatt period were discovered near Elgg and west of Bruggwingert. The Bachwiesen archeological site has yielded scattered finds from the Bronze and Roman eras. The Church (current building from 1863–65) was founded in 840 by the Emperor, and in 886 it was mentioned as the as principal church of the Counts of Linzgau. The nearby older cemetery at Sonnhalde dates from the 7th and 8th Centuries. In 890, Count Udalrich IV established a clerical community that was affiliated with the church, for the care of his burial place. But by 894/895 this community had already transferred to the Abbey of St. Gall. The right to appoint the priest, was acquired by the Lords of Bernegg before 1304. In 1318, these rights transferred to Hermann of Hohenlandenberg-Greifensee, in 1349-50 they went to Rüti monastery and after the monastery's secularization in 1525 the rights went to Zurich.
Our forefathers came with a vision and dream, to settle on this land
They built a great nation with blood and sweat, to benifit all of man
A path of destruction they did not see, they did not understand
Live for the moment instead of the future, typical for all of man
Chorus:
Overpopulation will soon take its toll
The growth of mankind is simply out of control
Soon no where to turn, we run short of precious land
Take our complex problems and place them in our children's hands
Living on a dream, a final prayer, future lies unseen
Hope to make a difference in our lives, its up to you and me
Destroying ourselves day by day, can we change at all
Hope for the best and keep on fighting before we take a fall
Repeat chorus
In the past, wars were benifical, man's its only enemy
Without this devastation we have inequality
People live longer thatn yeasterday, their offspring on the rise
It's mordern science, will it be answer or will it be our demise
Repeat chorus
Solo: Skowron
Repeat third verse
