FRANKFURT, July 8 (Reuters) - Italy's UniCredit has secured 47.6% of Germany's Commerzbank after a fraught takeover offer ended this month.

Like some other banks, Commerzbank has had a rocky history with big mergers and acquisitions over the years, including a long pursuit by UniCredit.

These are some of the key moments:

1870 to 1970s

Founded in Hamburg and later moved to Berlin. Relocated to Frankfurt in 1970 as one of Germany's leading banks, focusing on retail and corporate customers.

1970s

Expands to New York, London and other European capitals.

Commerzbank chairman and CEO step down, bowing to Cerberus demands.
