Tupac Adversaries - Biggie

"First off, f*ck your b*tch and the click you claim West side when we ride Come equipped with game You claim to be a playa But, I f*cked your wife We bust on Bad Boys ni**as f*cked for Life Plus Puffy tryin' to see me weak Hearts I rip Biggie Smalls and Junior Mafia some mark a** b*tches."
"You cross-eyed, Down syndrome, Crack baby ... Heard they call you Big Poppa ni**a how yousa figure Cause to me You'll always be a phony fat ni**a."

The Notorious BIG a/k/a Biggie Smalls used to be friends with Tupac before Pac got shot and robbed in New York in 1994. Notorious BIG was supposed to be a member of the group Thug Life and he also recorded several tracks with Tupac, such as Runnin (from the Police) which also featured Dramacydal. Tupac helped Biggie to start his career and let him come on stage when Tupac had concerts, which helped Biggie to become well known in New York.
Tupac said that Biggie never intended to sign with Bad Boy Records when he was with Thug Life, on the contrary, he didn't like Sean Combs. At the set of Poetic Justice, Tupac used to play Biggie's first single Party and Bullshit but he told Biggie to change his style because he could only have success by rapping songs "the bitches" would like. After that, Biggie changed his style from Party and Bullshit" to "Big Poppa".

Biggie signed with Sean Combs' label and released the CD Ready to Die which mainly dealt with death. Tupac said that the album sounded like his upcoming album Me Against the World. Therefore, Tupac changed the whole album.

The beef finally broke out when Tupac was shot in New York. He was supposed to recorded a song with Lil Shawn that night and a lot of NY rappers were there, including Biggie. When Tupac entered the Squad Recording Studios building, two men, dressed in army fatigues attacked him, Stretch Walker and Zaid Shakur with guns. Tupac was robbed and shot five times. Tupac said that Biggie set him up. He didn't mean that Biggie was behind the shooting, but Tupac was sure that Biggie knew about the battery which took place that night. Tupac was angry because Biggie didn't warn him or help him after the shooting.

While Tupac served time in jail, Biggie and a lot of other people gave him shout outs. Tupac thought that Biggie was trying to take his position. Biggie became a very popular rapper while Tupac was in jail, which confirmed his hypothesis. When Tupac was bailed out by Interscope Records and Atlantic Records to sign with Death Row Records, he started to take shots at Biggie in his songs. The most popular song is probably Hit Em Up, in which Tupac claimed that he had sex with Biggie's wife Faith Evans shortly after his release from jail.

First off, fuck your bitch in the click you claim
Westside when we Ride come equipped with game
You claim to be a player but I fucked your wife
we bust on Bad Boys niggaz fuck for life
-Hit Em Up

You bitch niggas
Gettin' blown away
You cross-eyed
Down syndrome
Crack baby
So you and Puffy are tough
Now that's crazy
I got your ass in my sight
Niggas dyin' tonight
-Hit Em Up 2

The Notorious BIG never dissed Tupac in public, he rarely mentioned him in songs, e.g. in a song called Brooklyn's finest, a collaboration with Jay Z:

If Faith had twins,
she'd probably have two Pac's
Get it, Tupac's

The Notorious BIG was murdered on March 9th, 1997 in Los Angeles/CA. He was shot by a yet unknown assailant.
