In 2008 National League Three was rebranded to the Rugby League Conference and expanded to include several regional competitions including the RLC Yorkshire Premier, which grew to three divisions.
Many clubs playing in the traditional winter leagues began to switch to the summer RLC, which contributed to its rapid growth.
Following the switch to summer the CMS Yorkshire League folded with clubs wanting to continue playing in winter joining the Pennine League.
Yorkshire based clubs who wished to play summer rugby were entered into the newly formed Yorkshire Men's League.
[1][2] The Yorkshire Men's League currently runs seven divisions with promotion and relegation between them: They also runs two separate leagues separate from the main competition:[citation needed] Source:[3]
