Ok here are mine. I have two, the period where Scarfo reigned in Philly. Like a movie or something, murders all over the place, colourful characters, and the most lucrative time arguably for the family. How they haven't made a movie on this yet is unbelievable.
My other is the Gambino family in the 1980s. For half the decade you had the old school, traditional running of the family in Castellano and the other half the yuppie "look at me" approach of Gotti. Fascinating characters also, the DeMeo crew, the white and blue collar factions and a split in the family, culminating in the hit on Castellano which was like a scene from a movie.
So what are yours and why?

The more recent years. Like 2000 to the present. The mob, from the 1930's through the 1990's has been covered sufficiently from any number of sources. Going back to the early part of the 20th century, and late 1800's, sort seems sort of futile beyond a certain point. From 2000 to the present is now, is happening, and is continually moving. Personally, I think it's fascinating to watch the families that still tread water, while observing the decay overall.

From 1979 until the mid-90's.

I was on Knickerbocker when Galante got whacked. But I was all the way over on Harman or Greene. Galante expired down on Jefferson and Knickbocker. But since then, I've been fascinated with the mob.

Cool you were there. my grandfather was down there working that summer he said tgat it was packed in he streets

I have a different one every week. Right now I'm most interested in Youngstown from the late 1950s, when all the mafia murders started, until 2002, with the defection of Strollo and the conviction of Traficant. Reason being is because it's close to where I'm from, mainly.

My usual favorite is the Capone era though; it's the one I keep going back to after being diverted by the Scarfo era, DeMeo era, etc.

I predict that the "winners" of this thread will end up being a tie between the DeMeo and Scarfo eras, thanks to the excellent books written about them. There are probably all sorts of crazy, fascinating mob stories we don't know much about, simply because a George Anastasia or a Martin Scorsese or someone like that hasn't come along to tell those stories properly in book or movie form. The DeMeo story would be just a boring list of murders if it had been recounted by a hack author.

The Mob was at its height of power.
