UFC 30: Battle on the Boardwalk was a mixed martial arts event held by the Ultimate Fighting Championship at the Trump Taj Mahal in Atlantic City, New Jersey on February 23, 2001. UFC 30 was also the first UFC event since UFC 22 to see a home video release.

The card was headlined by two Title Bouts, a Middleweight Championship Bout between Tito Ortiz and Evan Tanner, and the first UFC Bantamweight Championship Bout between Jens Pulver and Caol Uno. Following UFC 31, Bantamweight was renamed "Lightweight" under the new Unified Rules of Combat, defined by the Nevada State Athletic Commission. Bantamweight fighters would not again appear in the UFC until after the UFC-WEC merger in 2011. The event featured the first UFC appearances of Phil Baroni, Sean Sherk and Elvis Sinosic.

UFC 30 marked a major turning point for the UFC, as it was the first UFC event held by new owners Zuffa LLC. Headed by Station Casinos owners Frank and Lorenzo Ferttita, and managed by Dana White, Zuffa acquired the UFC in January 2001 from former owners SEG, who were on the brink of bankruptcy.

Caol Uno (宇野薫, Uno Kaoru^?) (born May 8, 1975) is a Japanese mixed martial artist, and former Shooto Welterweight Champion. Specifically, Uno is known for his low single leg takedown and rear naked choke.  He was born in Kanagawa, Japan. He holds notable victories over Mitsuhiro Ishida, Din Thomas(x2), Yves Edwards, Ivan Menjivar and Dennis Hallman.

Uno finished second in the All Japan amateur Shooto tournament in 1996. He was a runner-up in the submission wrestling world championships at ADCC losing in the finals to world-renowned Jean Jacques Machado.

Uno rose through the ranks of the Shooto mixed martial arts organization in Japan. In May 1999, Uno fought the then-legendary Rumina Sato. The fight was hailed as "Fight of the Year", an extremely fast-paced back and forth battle with a wide variety of stand-up and grappling exchanges.^{[citation needed]} Eventually, Uno took the back of Sato and choked him into submission.

The two rematched in December 2000. This fight concluded with Uno throwing Sato on his back, then striking him with a combination of kicks and punches, eventually knocking him out.

Jens Johnnie Pulver (born December 6, 1974) is an American mixed martial artist (MMA). He was the first Ultimate Fighting Championship (UFC) lightweight champion and was a coach on the The Ultimate Fighter 5 reality show, which aired on Spike TV. He was formerly signed as a featherweight with World Extreme Cagefighting (WEC), which is owned by Zuffa (the parent company of the UFC). Pulver holds notable wins over BJ Penn, Caol Uno, Cub Swanson and Dennis Hallman. He is one of only two men to defeat Penn at lightweight, the other being former UFC Lightweight Champion Frankie Edgar.

The son of a licensed horse jockey, Jens Pulver grew up in Maple Valley, Washington (approximately an hour's drive from Seattle). He was the oldest of four children (two brothers, Dustin and Abel, and one sister, Jamaica). Pulver has heterochromia, a harmless medical condition that gives eyes different colors; in Pulver's case his right eye is blue, while his left eye is brown.

Pulver was raised in what he referred to as a "daily hell." His childhood house was one of continual violence and abuse, stemming mostly from his alcoholic father. Many examples of the abuse Pulver faced as a youth are depicted in his autobiography, Little Evil, One Ultimate Fighter's Rise to the Top, the most extreme of which include an incident where his father threatened the then-seven-year-old Jens by placing a gun in Jens' mouth and then removing it, stating, "Shit, ain't worth a bullet."

Lyoto Carvalho Machida (Portuguese pronunciation: [liˈotu maˈʃidɐ]; born May 30, 1978) is a Japanese-Brazilian mixed martial artist from Salvador, Bahia, Brazil who fights as a light heavyweight in the Ultimate Fighting Championship. He is a former UFC Light Heavyweight Champion and is currently ranked as the #6 light heavyweight fighter in the world by Sherdog, MMAWeekly and Yahoo! Sports.

Machida was born in the city of Salvador as the third son of the highly ranked head of the Brazilian branch of the Japan Karate Association, Shotokan karate master Yoshizo Machida. Yoshizo moved to Brazil from Japan when he was 22 years old. There he met and married Lyoto's mother, Ana Claudia. Growing up in Belém, Lyoto began training in karate at the age of three and earned his black belt at the age of thirteen. He also began training in sumo at twelve and Brazilian Jiu-Jitsu at fifteen. He won a number of amateur karate tournaments, including the 2001 Pan American Karate tournament.

He was the runner-up in the 2000 Brazilian Sumo Championships in the 115 kg division. As an adult, he became Brazilian Champion twice under Taylor Swanson, and placed second in the South American Championship. He defeated American black belt Jiu-Jitsu fighter Rafael Lovato Jr. at L.A. Sub X. In addition to his sumo and karate achievements, he has a college degree in Physical Education. Lyoto's brother, Chinzô, is a Shotokan vice-champion (Australia 2006), losing only to number-one ranked Shotokan master Koji Ogata. Lyoto and Chinzô fought in a Karate Final 10 years ago in which Lyoto gave Chinzô a cheek scar that still exists today. His other brothers include Kenzo Machida, a TV journalist for one of Brazil's biggest TV stations, Take Machida and adopted brother Francisco Machida.

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, backing vocalist, and keyboardist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.

The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.
