Södermanland ( or ), locally Sörmland, sometimes referred to under its Latin form Sudermannia or Sudermania, is a historical province or landskap on the south eastern coast of Sweden. It borders Östergötland, Närke, Västmanland and Uppland. It is also bounded by lake Mälaren and the Baltic Sea.

Södermanland means "(The) Land of the Southern Men", where the "southern men" (södermännen) were the people living south of Uppland.

Administration 
The traditional provinces of Sweden serve no administrative or political purposes, but are historical and cultural entities. There is a corresponding administrative Södermanland County. However, the bulk of the population is within Stockholm County.

Heraldry 
The coat of arms was granted in 1560. The arms is represented with a ducal coronet. Blazon: "Or, a Griffin rampant Sable beaked, langued, membered and armed Gules." The same CoA was granted for the county in 1940.

Geography 

Södermanland is situated between lake Mälaren to the north and the Baltic Sea to the south and east. In the south, the border to Östergötland is comprised by the Kolmården forest.

The terrain is flat, with its highest altitude being Skogsbyås at  elevation. The terrain largely consists of water filled hollows covered with woods on the heights.

There are three major water regions. One in the west, where lake Hjälmaren drains into Mälaren. There is a second water region on Södertörn, which is rather small in size and has no larger lakes. Smaller lakes in that region include Bornsjön (), Orlången (), and Magelungen () as well as Naten lake. The third region is to the south towards Kolmården.

Both the city of Stockholm and Stockholm County are divided in the middle between Södermanland (southern part) and Uppland (northern part).

History 
Södermanland is one of the ancient Swedish provinces. People probably settled there in the early Stone Age, from which time the earliest remains date. There are a total of 96,000 known ancient remains such as grave fields, coins, knives, etc. There are prominent finds especially from the Neolithic, but also a substantial amount from the Nordic Bronze Age. From the early Iron Age, before 1 AD, the finds are however more sparse. Then from the 5th and 6th centuries AD, the finds are again plenty, now of gold. In 1774, a treasure of  of gold from that time was found on a farm in Tureholm.

From the Viking Age 300 runestones remain, second only to Uppland in quantity. The oldest, which is dated from the late 6th century, is the Skåäng Runestone.

The earliest recorded history is generally of the legendary kind. Before the 7th century it is deemed to have been governed by petty kingdoms. This period ended when Ingjald the Ill-Ruler allegedly had a number of local rulers arsoned around 640.

Nyköping has remnents of city structures in the archeological record from around 600. The excavated remnants if buildings were of several types with boat houses for longboats, according to the excavations 2010-2011 at Åkroken 3 (Report 2016:77). The boat houses were in use for about 400 years, during vendel era and viking age.

The oldest city with the historical city status in Södermanland was Södertälje, a privilege granted around 1000. Nyköping received the privilege in 1187. In the 13th century, Stockholm was granted the privilege; in the 14th century followed by Strängnäs, Torshälla and Trosa.

Around 1100, Strängnäs became the episcopal seat with a bishop and cathedral. It was for a long time the only diocese of the province. In 1942 the Diocese of Stockholm was established, claiming parts of the Strängnäs territory.

The first affirmative records date from the 13th century. King Magnus Ladulås was given the province in 1266, and settled himself on the manor at Nyköping. Nyköping became one of the most important cities in Sweden. In 1317, Nyköping become the location of the infamous Nyköping Banquet where King Birger had both his brothers murdered to take possession of the crown and avenge earlier wrong-deeds.

In 1523 the King Gustav Vasa, referred to as the Sweden's Father of the Nation, was crowned in Strängnäs. The date, 6June, eventually is commemorated as the national holiday. Charles IX, a son of Gustav Vasa, favoured the province, fortifying castles and establishing early industries.

The largest of very many paintings made by David von Krafft is the Hildebrand family portrait from 1713 (at Nynäs Manor, in Södermanland), depicting the merchant and industrialist Henrik Jacob Hildebrand and his wife Anna Sofia Amya on the occasion of their 50th anniversary surrounded by their over twenty children and grandchildren, as well as some deceased relatives in paintings on the wall in the background.
