The world's second-largest firm by headcount is Baker & McKenzie, also an international force with offices in Saudi Arabia and Myanmar as well as more traditional venues. Baker & McKenzie has 4,300 lawyers and gross revenue of $2.54 billion.

Given the wave of mergers that has swept through the legal industry it is no surprise that Dentons itself a product of mergers. U.K.-based Denton Wilde Sapte merged with U.S.-based Sonnenschein Nath & Rosenthal in 2010 to form SNR Denton. Then, in 2013, SNR Denton merged with Canada's Fraser Milner Casgrain and the French firm Salans to form Dentons.
