The civil ensign (also known as "merchant flag" or "merchant ensign") is the national flag flown by civil ships (merchant ships and others, as opposed to military) to denote nationality.
Countries may have a national flag for most purposes on land, a distinct civil ensign for non-military ships, and a naval ensign for the navy; sometimes two or all of these flags are identical.
In most countries there was originally no distinction between the flag for armed state ships (navy) and private owned, usually unarmed ships (merchant marine).
Today many countries, including the United States and France, continue the practice of having a single national flag for all or most purposes.
In other countries a distinction is made between the land flag and the civil and naval ensigns.
Most notable for the elaborate flag system is the United Kingdom, that uses the Union flag on land, (inter alia) the Red Ensign for merchant ships, and the White Ensign for the Royal Navy.

In the second half of the 1970s, DDG Hansa invested large amounts of money updating the fleet and diversifying; a bad economic climate and the weakness of the U.S. dollar against the mark then led to financial difficulties.
Attempts by the company to reduce high labour costs by "outflagging" ships to the Philippines flag were not sufficient to staunch losses, even though its foreign flag fleet was profitable.
Deutsche Bank and two insurance companies came to own 80% of the company; in 1979, its financial assets were sold to Hapag Lloyd; and the loss of business in Iran as a result of the 1979 revolution finally caused the company to file for bankruptcy on 18 August 1980.
The company ceased operations by 31 December that year.
The ships were taken over by other companies, the lines and the container business by Hapag-Lloyd, the platform service business by VTG, and many of the heavy lift ships were sold to a Greek owner who used the name 'Hansa Heavy Lift' and changed the names of the ships to end in -"bels".
The brand name DDG Hansa was sold in 1984 to Project Carries and is now owned by Deutsche Seereederei of Rostock, operating as Interhansa AG (previously Reederei Hansa AG).

It is never flown by ships at sea, nor on outdoor flagpoles on naval land installations, and is not used as an identifying mark of U.S. Navy ships and facilities, as is the U.S. Coast Guard ensign.
