Perhaps you should try some spelling variations:
"its decolonization from" » "its decolonisation from", "its decolonization africa", "its decolonization across", "_ decolonization from", "box decolonization from", "war decolonization from"
"its colonization failed" » "its colonization still", "its organizations failed", "anti colonization failed", "jews colonization failed", "mars colonization failed"
"its cooperation history" » "its corporation history", "its federation history", "city cooperation history", "et cooperation history"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"its decolonization from\") OR (\"its colonization failed\"))) OR (\"its cooperation history\"))~".
• Removing quotes may allow a broader search: (((( its decolonization from ) OR ( its colonization failed ))) OR ( its cooperation history ))~.
• Adding a wildcard symbol may retrieve word variants: (((("its decolonization from") OR ("its colonization failed"))) OR ("its cooperation history"))*.
