There seems to have been a deep-seated yearning for a 'strong man', a loathing of democratic politicians (parliamentarians) and an utter Horror of Bolshevism.

The European Union was founded by Western European countries while Eastern European countries were still occupied by the Soviet Union.
No Eastern European countries were members of the European Union in 1993. The EU did not expand to the east until 2004 when nine Eastern European countries (with one Western European nation) joined the EU.
Eastern Europe is only full of Eastern European countries. That means there are no Western European countries, Latin American countries, Subsaharan countries, East Asian countries, etc. in Eastern Europe.
Eastern European countries became communist, which was a political ideology modernized by the USSR.
Many countries from Eastern Europe have joined the European Union since 2004. This makes it easier for them to travel to other European countries to get work. A lot of people from eastern European countries have travelled to countries in western Europe where there is more work, so a lot of eastern Europeans have gone to the United Kingdom.
Young eastern European democracies are at an increased risk for turmoil during a global recession due to factors such as reliance on foreign investment, high levels of debt, limited economic diversification, and political instability. These countries may struggle to manage the economic challenges of a recession, leading to social unrest, political polarization, and potential erosion of democratic norms.
Eastern European countries have more environmental issues, such as the Ukraine, Russia, or Romania.
