Diplomaticos was initially created in 1966 as a less expensive alternative to the Montecristo and aimed towards the French cigar market at lower prices then Monstrecristo. Diplomaticos is one of the few Havana brands which is exclusively dedicated to hand-rolled cigars.

The Diplomaticos line mimics the original Montecristo line in having five numbered sizes, all handmade. The blend used for this line is milder than that used for Montecristo, most likely to cater to the taste of French cigar smokers, and nowadays is usually still a bit cheaper in price than corresponding Montecristo sizes.
