If the postseason history between the Boston Bruins and the Montreal Canadiens was a book, it’d be as long as “War and Peace.” The Eastern Conference semifinal series that began Thursday night at TD Garden is the 34th playoff series between the two teams.

String together all of the playoff games against each other — just the playoff games, an NHL record 170 before this series — and they’re equal to more than two complete NHL seasons. Toronto and Detroit are next on the list and they’re still more than 50 games behind.

Bruins coach Claude Julien has seen the rivalry from both sides. He was the head coach in Montreal from 2003 to 2006.

“I hated Boston when I was in Montreal,” Julien said. “Now I hate Montreal ’cause I’m in Boston.”

The Bruins and Canadiens played their first playoff series in 1929. Boston won that matchup, but from 1946 to 1987, Montreal dominated Boston in the postseason — winning 18 consecutive series. Things have been more even since then. And in 2011 — in their last postseason meeting — the Bruins prevailed in an epic, seven-game, opening-round series on their way to winning the Stanley Cup. Julien said the intensity of the rivalry makes his job easier and harder.

“As a coach, you don’t have do much of a pep talk when it comes to playing each other,” he said. “It’s more about controlled emotions, making sure that the rivalry is what it is, but that your game still remains a game that is under control.”

Bruins forward Patrice Bergeron said having an archrival is a bonus for everyone.

“I think it’s great for the fans, great for us as players,” he said. “Gets you going, gets you emotionally even more attached to games and you want to win that much more.”

“I hated Boston when I was in Montreal. Now I hate Montreal ’cause I’m in Boston.”

Bergeron has spent the last decade in a Bruins uniform. On the other end of the spectrum is one of his newest teammates: Justin Florek. It’s been a wild couple of weeks for the rookie. After Boston’s five-game series against Detroit, Florek had skated in more playoff games than regular season games. He grew up in Michigan, rooting for the Red Wings, then scored his first career playoff goal against them. But Florek’s well aware of the significance of Boston versus Montreal.

“Oh, it’s huge,” he said. “From a fan perspective, you grow up watching these kind of series and you see how intense they are on TV. Just the rivalry between the two teams and now I get to play in a series like this. It’s just going to be unbelievable.”

The past few years have only amplified the feud. In 2011, Bruins captain Zdeno Chara checked Montreal’s Max Pacioretty, who smashed into a stanchion near the benches and suffered a concussion and fractured vertebra. The league chose not to suspend Chara, which angered Montreal fans. This season, on something of a freak play, Pacioretty hit Boston’s Johnny Boychuk into the boards. Boychuk was taken to a hospital. In the end, the defenseman wasn’t seriously injured, but it’s another moment that can be viewed differently north and south of the Canadian border. As for Boychuk, he says the stakes are too high to risk the penalties that can come from frustration.

“It’s playoffs and you keep your anger and your personal vendettas at the door and take it for the team,” he said.

The Bruins had a few days to practice and rest after eliminating Detroit in Game 5 last weekend. The Canadiens’ lightning quick four-game sweep of Tampa Bay gave Montreal more than a week off before Thursday’s Game 1 matchup in Boston. Claude Julien said both teams opened the playoffs at a high level.

“Montreal had a great series against Tampa,” he said. “Anybody who watched that series recognized that. We’re a group right now that feels good about our game, but we’re that same group that understands that we have a tough series ahead of us.”

The ending hasn’t been written yet, but the 34th postseason series between Boston and Montreal is certain be another heated chapter in hockey’s greatest book.
