How did the Knights Templar end?

They didn't. They stopped wearing armour and charging about on horseback in battles, but they are still the aristocracy of Europe today.

In Britain and other parts of Europe knights still exist today and Her Royal Highness the Queen of England knights more people every year. Britain still has Colleges of Arms to control the design, issue and use of heraldry (it is still an extremely serious offence to illegally use a coat of arms that you are not entitled to).

Some knighthoods are hereditary, being passed on to the eldest son and his eldest son and so on down the generations. Others are limited to the lifetime of the individual - as in the case of celebrities, actors, sportsmen and others who are knighted by the queen.

Take the example of Harry Secombe, a famous Welsh entertainer, singer and comedian who sadly died in 2001. He was knighted in 1981, being awarded an heraldic coat of arms and his own motto by the college of Arms. He was then Sir Harry Secombe, an English knight.
