PRAGUE -- Gustav Husak, 78, who replaced pro-democracy reformer Alexander Dubcek in 1969 and led Czechslovakia during two decades of Communist orthodoxy, died Nov. 18 in a hospital in the Slovak capital of Bratislava. He had cancer.

He replaced Dubcek as Communist Party general secretary in April 1969, eight months after Dubcek's effort to build "socialism with a human face," was crushed by a Soviet-led Warsaw Pact invasion.

With Soviet backing, Mr. Husak purged the party's ranks of more than 500,000 reformist members and reimposed communist orthodoxy on Czechoslovakia for the next 20 years.

In 1975, he became state president while continuing as party general secretary until 1987. He remained president until Dec. 10, 1989, when he was forced to resign by the "velvet revolution" that had suddenly thrown off decades of Communist rule.

When Mr. Husak took over the country, it was deeply embittered by the Warsaw Pact invasion of August 1968. He pledged to continue Dubcek's work in creating "socialism with a human face."

But he soon abandoned his promise under strong pressure from Moscow and from a powerful hardline faction that blocked attempts to reform the country's political and economic structures.

Over the years, he concentrated largely on improving economic conditions as a way of deflecting demands for greater individual freedoms and political reform. His unswerving loyalty to Moscow, accepting Soviet troops and medium-range nuclear missiles on Czechoslovak territory, gained him high favor in the Kremlin.

In 1988 the Presidium of the Supreme Soviet awarded him the Order of Lenin, the Soviet Union's highest honor.

Only in early 1987, after Mikhail S. Gorbachev rose to power in Moscow, did Mr. Husak accept the need for genuine change. But Czechoslovakia, one of the more conservative East Bloc states, continued to lag behind as calls for democratic reform swept Eastern Europe in the second half of 1989.

His last task before leaving the presidency was to swear in the country's first government since 1948 that was not dominated by Communists.

A native Slovak, he was once jailed by the Communists for seeking more autonomy for the poor eastern region of Czechoslovakia. Yet he eventually rose to the highest levels of power and saw his ideas of communism and Slovak sovereignty shape Czechoslovakia through several generations.

Czechoslovakia's constitution was revised in 1968 to make it a federation of two nations -- Czech and Slovak. But since the fall of communism, Slovak leaders are criticizing that structure as Czech-dominated and once again are seeking more autonomy.

The huge investments that poured into Slovakia during Mr. Husak's rule were designed to boost the republic's heavy and military industry. But they turned out to be lethal for the Slovak economy now that it is being demilitarized and privatized under post-Communist market reforms.

Mr. Husak was born Jan. 10, 1913, into a Bratislava peasant family. He combined teaching and work in a factory with studies for a law degree.

He joined the Communist Party in 1933 and remained in the organization -- by then declared illegal -- during the Nazi occupation. He helped lead an abortive Slovak national uprising in 1944.

After the war, he eventually became one of the more sophisticated advocates of communism in his eastern republic.

He was arrested by Communist authorities in 1951 as a potential troublemaker for seeking more autonomy for Slovakia, but was released in 1960 and publicly rehabilitated and readmitted to the party.

After his release, he was employed as a construction worker and began a gradual political recovery.

His rehabilitation in the party was partly helped by fellow-Slovak Dubcek. In January 1968, he was made a deputy prime minister under Dubcek, who was by then overall party leader.

Mr. Husak's party membership was suspended in 1989, and he was expelled from the party for a second time in 1990.

After being ousted, he led a secluded life in his Bratislava home. He was hospitalized Nov. 8 and died one day after the second anniversary of the student protests that sparked the velvet revolution.

He had two sons by his first wife, who divorced him while he was in prison. His second wife died in a helicopter crash in 1977.

Earlier this month, the former Communist Party leader received last rites from Roman Catholic Archbishop Jan Sokol.
