Iggy Azalea vs. Azealia Banks The battle of the Azaleas started in 2012, when Banks called out XXL magazine for placing Iggy on its 'Freshman' cover after she spit lyrics like 'runway slave master' on one of her tracks. In 2014, Banks called out Iggy for being quick to appropriate black culture while staying silent went it comes to black issues -- like the police shooting of Mike Brown. She also called her 'Igloo Australia.' Iggy hit back with a Twitter rant, calling Banks 'poisonous' and blaming her lack of success on her 'piss poor attitude.'

Meek Mill The Philly-based rapper called out in a tweet in 2015, claiming the 'Views' artist wasn't promoting Meek's 'Dreams Worth More Than Money' album -- on which he was featured -- because doesn't write his own raps. The Canadian rapper shot back with two diss tracks, 'Charged Up' and 'Back to Back,' in the same week. Meek Mill fired back with his own 'Wanna Know.' The feud still appears to be active, as released 'Summer Sixteen' earlier this yeah, which was perceived as another track aimed at Meek Mill.

'I'll turn Friday into Friday the 13th, Alright you Little Kim clone clown,' Queen Bee rapped. Nicki threw subliminal shade at Kim during her 2015 BET Awards acceptance speech.

Although she never mentioned her by name, many took it as a direct slam: “Please make it your business to follow your dreams because one day, you will wake up and look around and your dreams will be gone. And then you’ll be mad at somebody, but be mad at your f------ self,' Minaj said. Getty Images •. This beef turned violent, with alleging that 50 was behind a robbery of the 'Holla Holla' rapper out of what he called jealousy. 50 was then attacked by 's Murder Inc. In a New York recording studio where he was stabbed. Investigators also believed Murder Inc.

Foxy Brown Lil' Kim and Foxy Brown's careers took off around the same time, fueling rumors that there were tensions between the two -- especially when their debut albums were scheduled for release a week apart. Then Kim put out 'Notorious K.I.M.,' on which she took implicit shots at Foxy, who then fired back with some lines of her own. The beef eventually took a violent turn when shots rang out as Kim left Hot 97's studios following a run-in between her entourage and Capone from Capone-N-Noreaga.

On it, he said Nas 'went from Nasty Nas to Esco's trash'and rapped, 'Ask Nas, he don't want it with Hov.' Then all hell broke loose because Nas definitely did want it with Jay-Z, releasing 'Ether,' which attacked HOVA's street cred and more. As the two top rap artists at the time, Nas and Jay-Z were essentially embroiled in a power struggle for hip-hop supremacy, but now the two are besties -- kinda.

Wrote almost all of the lyrics on N.W.A's debut album 'Straight Outta Compton,' but reaped none of the monetary benefits, so he split from the group, which later released a diss track targeting the newly-solo rapper. Cube naturally came back with his own expletive-laden diss track, 'No Vaseline,' searing his former bandmates with a flurry of snaps that comprised an in N.W.A biopic 'Straight Outta Compton.' The death of group member Eazy-E marginalized the beef, which is now long squashed, with Cube and the remaining members of N.W.A.
