The original fan group — known as the Southern Legion — was also the largest, with more than 400 dues-paying members. But last year it sought to rename itself The Siege.

“We felt a change was appropriate once we saw the crest,” said Max Ramos, a founding member of the Southern Legion. “A group of herons is called a siege. It felt right.”

Those who felt otherwise split off and kept the original name. Ramos insisted there were no hard feelings. The amicable split, he said, is a sign of the camaraderie that has helped fans remain steadfast in their dedication to Beckham’s grand, but at times excruciatingly fluid, plan.

There is no turning back at this point, anyway. Last year, Beckham and his new group of well-financed, well-connected investors were finally granted the rights to an expansion place in the league. Satisfied that doubts about a stadium plan and the Beckham group’s resources and local commitment had been resolved, the commissioner confirmed that the team would enter M.L.S. in the 2020 season.

The matter of where it will make that debut, however, is a bit more complicated.

Inter Miami has been the focus of a stream of legal action in recent months, with issues including an ethics complaint related to the owners’ political lobbying, disputes about the feasibility of building a stadium on its preferred site and the legality of public votes on the matter.
