BEIJING — The police detained more than 100 members of an underground Protestant church on Sunday after the congregation tried to pray in a public plaza in the north of the capital.

The raid on the church, which sought to pray outside after it was evicted from its building under government pressure, was part of a broad crackdown on dissent over the last seven weeks. The campaign has led to the jailing of scores of rights lawyers, writers and activists, as well as the repression of unauthorized worship.

The authorities have also clamped down on less obvious threats, canceling events as diverse as a St. Patrick’s Day parade and a collegiate debate tournament this weekend.

The Protestant church, Shouwang, was evicted last week from the space it was renting after the government pressured the landlord not to renew the lease. The congregation, whose 1,000 members make it one of the largest unregistered churches in China, has been seeking legal recognition since 2006.
