Question: Preston North End Football Club, an English association football club based in the Deepdale area of Preston, Lancashire, was founded in which year, they were the only team to be known by this nickname for 115 years until Arsenal completed their 2003–04 season without a defeat?

<P0-S0>  For their first eight years, there was no league football, so matches were arranged on an occasional basis, supplemented by cup competitions organised at both local and national level. <P0-S1>  In 1888, Preston participated in the inaugural Football League. <P0-S2>  They won the first top-flight league title and of the 22 matches they won 18 and drew the other four, therefore they remained undefeated thus being labelled "The Invincibles". <P0-S3>  They were the only team to be known by this nickname for 115 years until Arsenal completed their 2003–04 season without a defeat. <P0-S4> Preston North End Football Club, an English association football club based in the Deepdale area of Preston, Lancashire, was founded in 1880. <P0-S5>  Since then the club has remained in the Football League although it has competed in its various divisions. <SEP> <P1-S0> Arsenal Football Club is an English professional association football club based in Holloway, London. <P1-S1>  The club was formed in Woolwich in 1886 as Royal Arsenal before it was renamed Woolwich Arsenal in 1893. <P1-S2>  They became the first southern member admitted into the Football League in 1893, having spent their first four seasons solely participating in cup tournaments and friendlies. <P1-S3>  The club's name was shortened to Arsenal in 1914, a year after moving to Highbury. <P1-S4>  In spite of finishing fifth in the Second Division in 1915, Arsenal rejoined the First Division at the expense of local rivals Tottenham Hotspur when football resumed after the First World War. <P1-S5>  Since that time, they have not fallen below the first tier of the English football league system and hold the record for the longest uninterrupted period in the top flight. <P1-S6>  The club remained in the Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League, of which they were an inaugural member. <P1-S7>  In 2003–04, Arsenal completed a league season without a single defeat, something achieved only once before in English football, by Preston North End in 1888–89. <SEP> <P2-S0> The 2003–04 FA Premier League (known as the FA Barclaycard Premiership for sponsorship reasons) was the 12th season of the Premier League. <P2-S1>  Arsenal were the champions and Chelsea, who had spent heavily throughout the season, were the runners up. <P2-S2>  Arsenal ended the season without a single defeat – the first team ever to do so in a 38-game league season and the second team overall (the first was Preston North End in 1889, 115 years earlier, during a 22-game league season). <SEP> <P3-S0>  It began on 1 July 2003 and concluded on 30 June 2004, with competitive matches played between August and May. <P3-S1> The 2003–04 season was the 109th in the history of Arsenal Football Club. <P3-S2>  The club ended the Premier League campaign as champions without a single defeat – a record of 26 wins and 12 draws. <P3-S3>  Arsenal fared less well in the cups, eliminated in the FA Cup and League Cup semi-finals to Manchester United and Middlesbrough respectively, and at the quarter-final stage of the UEFA Champions League to Chelsea.
