A spiritual tradition without some form of continuation after death is almost unheard of, even if that continuation is only via some kind of life force. There are the Carvaka and Lokayata schools of Hinduism that were supposedly materialist. However, we have no existing texts from them, and all the sources come from hostile opponents that have in turn been interpreted through a Western light.
The only spiritual tradition that definitely had a powerful contingent that denied continuation was Judaism. The Sadducees were a priestly class who ran the temples during the Second Temple period. They explicitly denied there was anything after death. All they had to do was follow the Torah to the word, and as it never mentions any kind of continuation, they didn't believe in it.
Today, many of the most famous hard-line materialists and atheists have Jewish heritage. We have been sold a lie that we know in our hearts is false, and which makes us think we are soulless bugmen, even when we know deep down that we are not. Once you make the connections here, you realise why the modern world is as it is.
