The idea for the rally and the march spread nationwide after the Texas legislature approved one of the most restrictive abortion laws in the country.
The abortion legislation will ban abortions at 20 weeks and require more strict practices at clinics.
The event is being organized by the International Socialist Organization.
The march is for people to show up, stand up, and march with Texas women.
Austin police escorted men, women and children marched down Congress Avenue, onto Lavaca Street, down 11th Street and ended up back at the Capitol.
They hope to spread the message that the fight is not over and they will not be silent about their beliefs.
One of the rally speakers, Holly Lewis, said, "I think that our elected officials and our appointed officials are sometimes put in a position where they are forced to listen...I think that it comes from people being organized in the street and I think if we organize and we stand together, we really can't lose."
Many know State Senator Wendy Davis as the Democrat who spearheaded a filibuster of the restrictive abortion bill.
According to figures her campaign expects to report to the Texas Ethics Commission Monday night, Davis raised $933,000 in the last two weeks of June. Combine that with 2012 funds and she's expected to have more than $1 million in the bank.
Davis, who is mulling a run for Texas governor, will likely run against Attorney General Greg Abbott, who reports having more than $20 million in the bank.
Texas hasn't elected a Democrat to a statewide office since 1994.
