The big-hitters relegated from the Championship were all in action, with Leicester City, Oxford United and Sheffield Wednesday harbouring hopes of an immediate return with lofty expectations on their shoulders.
Andy Woodman and Martin Patterson made their League One managerial bows with Bromley and Notts County respectively following promotion, with the experienced Neil Harris leading Cambridge United back to the level.
Also joining them from the basement EFL division were MK Dons, whose marquee additions bode well for a potential back-to-back promotion charge.
With five new managers in the dugout and a raft of teams vying to improve on their previous campaign, plenty of new additions across the division were in action as they looked to make their mark in their new colours.
Here are the key talking points from the opening weekend.
Notts County 1-1 Leicester City
Just five years ago, the Foxes had clinched their first-ever Emirates FA Cup following fruitful campaigns in both the Premier League and UEFA Europa League under Brendan Rodgers. Notts County meanwhile had fallen at the semi-final hurdle in the National League play-offs, recording the lowest finish in their history in fifth.
Nonetheless, the two have experienced contrasting fortunes since then, but nothing could separate the two sides.
Buoyed by a raucous Meadow Lane crowd, the hosts started strong but Leicester grew into the contest and took the initiative just after the hour-mark thanks to Jayden Joseph's thunderous strike from the edge of the box.
They are unsurprisingly title favourites, boasting a squad which is still sprinkled with Premier League quality, but they were shown the brutal realities of getting out of this division when the Magpies equalised nine minutes from time.
Emile Acquah's header from close range cannoned off the post but Conor Grant was on hand to bury the rebound as the spoils were shared.
Oxford United 2-2 MK Dons
Heading into his first managerial post with his hands tied by their ongoing off-field issues, Aaron Ramsey will have to adapt like a fish to water to his new venture to steady a sinking ship.
Ambitions of bouncing back to the Championship are a distant dream with the U's under a transfer embargo due to failing to comply with the EFL's salary cost management protocol (SCMP) regulations.
The visitors were in a jubilant mood following promotion last season, with the arrivals of the likes of Sam Nombe and Charlie Goode fuelling their bid to reach the second tier for the first time since 2016.
A siege mentality is what is required for Oxford if they are to get through this season, and that was on show in the opening exchanges as Mark Harris broke the deadlock inside 20 minutes.
The lead didn't last for long though, as Goode netted a towering header from a tight angle nine minutes later, before Aaron Collins completed the turnaround when the 29-year-old angled in Ryan Wintle's pinpoint delivery.
Oxford threw bodies forward in search of a leveller in the dying embers and the MK Dons backline were unable to resist Ciaron Brown's strike to initiate delirious scenes at the Kassam Stadium to ensure it finished honours even.
Reading 3-4 Luton Town
Luton were incredibly unfortunate to miss out on the play-offs on the final day of last season following a run of just one defeat in 17 matches, a stark contrast to their struggles under Matt Bloomfield earlier on in the campaign.
Under the leadership of Jack Wilshere in his first full season at Kenilworth Road, the Hatters are expected to be challenging in the upper echelons of the division, and their front-foot approach was certainly on show at Reading in a pulsating affair.
Jake Richards drew first blood on six minutes before a Jack Marriott hat-trick saw the hosts sail into a two-goal lead before the break.
The half-time interval came at the perfect moment for the Vertu Trophy holders, who came out with a renewed purpose, Kasey Palmer netting a two-minute brace to restore parity.
A remarkable comeback was complete seven minutes into additional time as, after striking the crossbar, the ball eventually came back to Gideon Kodua who powerfully dispatched past Joel Pereira.
If Luton's games are going to be this full-throttle this season, they will certainly be a side to keep a close eye on.
Best of the rest
To say Sheffield Wednesday were in turmoil last season was a seismic understatement, with their relegation all but confirmed before a ball had even been kicked. They have their sights firmly set on reversing those fortunes this season and Jamal Lowe's strike ensured they secured a 2-1 win at Leyton Orient.
Cambridge scraped past Wigan Athletic having held a three-goal cushion, with goals from Sonny Perkins and Akeel Higgins in the second period counting for nothing.
The spoils were shared in 1-1 draws between Blackpool and Wycombe Wanderers as well as Burton Albion against Stevenage, while Louis Reed netted the winner for Mansfield Town who ran out as 2-1 victors over Doncaster Rovers.
Beaten in the play-off semi-finals to eventual winners Bolton Wanderers last term, Bradford City were seeking revenge and kicked off their season in ideal fashion with a comfortable 2-0 win against Peterborough United.
Making their League One debut following two promotions in three years, Bromley made the trip to Barnsley and Victor Adeboyejo netted the only goal of the game on 70 minutes against his former employers to grab a shock three points.
Derensili Sanches Fernandes, a summer arrival from Dutch outfit Excelsior alongside right-back Ilias Bronkhorst, made an instant impact on his Huddersfield Town debut with a first-half brace to put AFC Wimbledon to the sword in a 3-0 victory.
Jimmy McNulty's new-look Stockport County got off to a flyer at title favourites Plymouth Argyle, securing a 3-1 victory as new signing Ryan Glover from Barnet endeared himself to his new supporters with a sublime strike from distance.
