One of the main treaties was called The

The treaty focused on two other key issues:

Self Determination
Germany would accept sole
responsibility for causing the war
Ethnic groups would vote on
which country to be governed by –
or if they wanted an independent
homeland

British/French retain and increase their
empires: their mandates became de facto
colonies.
Decisions, Shortcomings

Alsace-Lorraine returned to France
Polish Corridor created
Central Powers gave up colonies to Britain

The demilitarization of the Central Powers provided fuel
for future nationalism
Members of the League of Nations did not follow
through with military responsibilities, which limited the
effectiveness of the League to provide collective security
German pride hurt

Hitler would use this to overthrow new German
government
Though some mandates soon became independent
states, many remained de facto colonies which would
lead to several conflicts before and after WWII
