LONDON -- Europe's wealthiest individuals are a mixed group.

Some of them founded iconic international brands like Lego and IKEA, and some owe their billions to the wealth of centuries-old dynasties.

There are those in eastern Europe who made their money recently after the collapse of the Soviet Union, industrialists from Scandinavia with fortunes derived from old industry, and some in Western Europe with ancient royal connections.

Business Insider has used Forbes' 2017 Billionaires' List to determine the wealthiest individual in each European state, ranked from the least wealthy upwards.

In some countries, no residents made the Forbes list, and the countries were therefore not included in this ranking.

Monaco's Tatiana Casiraghi -- NET WORTH: £1.9 billion ($3.08 billion)

Beer heiress Tatiana Casiraghi is Monaco's richest resident, and she also happens to be a royal there. Casiraghi inherited the bulk of her fortune from her late grandfather, who sold his Colombian brewery Bavaria for billions in 2005. She is married to Prince Andrea Casiraghi of Hanover, who is fourth in the line to the Monaco throne.
