Megacorporation
The private Dutch East India Company, for example, operated 40 warships and had 10,000 private soldiers to monitor its farflung spice empire, while the British East India Company controlled a large colonial empire in the mid-19th century before the company was dissolved and its territories absorbed into the British Empire. The Hudson's Bay Company was once the world's largest landowner, exercising legal control and a trading monopoly on its territory known as Rupert's Land which consisted of 15% of the North American land mass.

Today many countries have competition laws (also known as antitrust laws) to prevent real-life corporations from having mega-corporation characteristics. On the other hand, some countries protect a certain industry deemed important by mandating that only a single company, usually state-owned, can operate in it. An example of the latter is Saudi Arabia, which gains the majority of its government revenues through its mega-corporation Saudi Aramco.
