Good immediate money was a very appealing option to many boxers who didn't have an abundance of options.

Amidst this boxing rise, things unraveled between the Hutches and the Kinnahans from 2014.

Jamie Moore, he was the trainer of Matthew Macklin, and he was shot in a case of mistaken identity in Port-au-Bonneuse, outside Marbella, as he left a party at the home of Kinnahan.

In 2015, Gary Hutch was murdered in Marbella by the Kinnahans.

Gary was the nephew of Gerry the Monk Hutch.

And in 2016, the feud would escalate in a way which dominated the news agenda and captured public attention.

Once again, boxing was to the fore.

A man has been shot dead at a boxing weigh-in in a Dublin hotel this afternoon.

The shooting took place at around half past two at the Regency Hotel in Drumcondra.

It was during a weigh-in for a boxing match that's taking place tomorrow evening.

Gardaí believe the gunmen were dressed in Garda uniforms or security uniforms and used semi-automatic weapons.

The Regency Hotel shooting has gone down in a kind of infamy in this country.

It's simply called the Regency shooting.

The hotel has had to change its name.

So that was February 2016, the weigh-in of an MTK fight.

It was, of course, a failed attempt on Daniel Kinnahan's life.

David Byrne, a long-time member of the Kinnahan gang, lay dead in the lobby.

The images were widely spread.

And back in the boxing world...

this couldn't be ignored.
