Q: He made his appeal while celebrating Mass in three native languages after a new Vatican decree approved their use.
The Pope also used the open-air service in San Cristobal de las Casas to warn about threats to the environment.
Throughout his five-day trip he has condemned the evils of forced emigration and drugs.
He has urged Mexico's leaders to provide "true justice" to suffering citizens.
But on Monday he drew attention to the suffering of indigenous people in his address in Chiapas state.
"On many occasions, in a systematic and organised way, your people have been misunderstood and excluded from society," the 79-year-old pontiff said after citing Popol Vuh, an ancient Mayan text.
"Some have considered your values, culture and traditions to be inferior. Others, intoxicated by power, money and market trends, have stolen your lands or contaminated them. How sad this is," he said.
"How worthwhile it would be for each of us to examine our conscience and  learn to say, 'Forgive me!'"
Correspondents say that while Chiapas is the country's least Roman Catholic state, tens of thousands of people attended an open-air Mass in a sports field in San Cristobal de las Casas.
Women wore colourfully embroidered dresses to deliver biblical readings and hymns in the Chol, Tzotzil and Tzeltal languages.
The pontiff highlighted the deep appreciation of indigenous people for nature and said their community had much to teach the rest of the world.
He also highlighted the need to care for the environment.
"We can no longer remain silent before one of the greatest environmental crises in world history," he said,
While Mexico is the world's second most populous Catholic nation after Brazil, only 58% are loyal to the Vatican in Chiapas in comparison to 82% in the rest of the country.
Mexicans hope papal visit brings change
On Tuesday, the Pope heads to the capital of the western state of Michoacan, a region scarred by drug violence.
The Pope concludes his five-day trip in Ciudad Juarez on the US border, a city which has also been blighted by drug-related murders. A Mass there will highlight the plight of migrants.

A: Pope Francis has asked Mexican indigenous people in Chiapas state for forgiveness over they way they have been excluded from society.

Q: The project is being developed at Google X, the company's clandestine tech research arm, which is also responsible for its self-driving car.
Project Wing has been running for two years, but was a secret until now.
Google said that its long-term goal was to develop drones that could be used for disaster relief by delivering aid to isolated areas.
They could be used after earthquakes, floods, or extreme weather events, the company suggested, to take small items such as medicines or batteries to people in areas that conventional vehicles cannot reach.
"Even just a few of these, being able to shuttle nearly continuously could service a very large number of people in an emergency situation," explained Astro Teller, Captain of Moonshots - Google X's name for big-thinking projects.
Google's self-flying vehicle project was first conceived of as a way to deliver defibrillator kits to people suspected of having heart attacks. The idea was that the drones would transport the equipment faster than an ambulance could.
"When you have a tool like this you can really allow the operators of those emergency services to add an entirely new dimension to the set of tools and solutions that they can think of," said Dave Voss, incoming leader of Project Wing.
The prototype vehicles that the company has built have successfully been tested by delivering packages to remote farms in Queensland, Australia, from neighbouring properties.
Australia was selected as a test site due to what Google calls "progressive" rules about the use of drones, which are more tightly controlled in other parts of the world.
Project Wing's aircraft have a wingspan of approximately 1.5m (4.9ft) and have four electrically driven propellers.
The total weight, including the package to be delivered, is approximately 10kg (22lb). The aircraft itself accounts for the bulk of that at 8.5kg (18.7lb).
The small, white glossy machine has a "blended wing" design where the entire body of the aircraft provides lift.
The vehicle is known as a "tail sitter" - since it rests on the ground with its propellers pointed straight up, but then transitions into a horizontal flight pattern.
This dual mode operation gives the self-flying vehicle some of the benefits of both planes and helicopters.
It can take off or land without a runway, and can hold its position hovering in one spot. It can also fly quickly and efficiently, allowing it to cover larger distances than the more traditional quadcopter vehicles available commercially.
The vehicles are pre-programmed with a destination, but then left to fly themselves there automatically.
This differs from many military drone aircraft, which are often remotely controlled by a pilot on the ground, sometimes on the other side of the world.
Eventually Google said it could use unmanned flying vehicles to deliver shopping items to consumers at home. That's a use that retail giant Amazon has already stated an interest in, with its proposed Prime Air service - the announcement of which generated headlines at the end of last year:
Amazon has asked the US Federal Aviation Administration for permission to conduct outdoor tests.
"The things we would do there are not unlike what is traditionally done in aerospace," said Mr Voss.
"It will be clear for us what level of redundancy we need in the controls and sensors, the computers that are onboard, and the motors, and how they are able to fail gracefully such that you don't have catastrophic problems occurring."
Other unusual vehicles have been investigated for humanitarian aid, including flying cars and hoverbikes, with the same aims of reaching cut-off areas quickly.
"We will have to see what kind of specific technology works best within the aid landscape, and if the new technology can integrate positively in the local context," said Lou Del Bello from news site SciDev.net, speaking about the category in general.
"It will need to demonstrate it can be cost effective, and respond to actual needs of local people."

Q: Don and Maxine Simpson from Bakersfield, California, died four hours apart on adjoining beds, holding hands during some of their final hours.
Melissa Sloan said her grandmother died first and when her body was removed from the room, her husband followed.
"All Don wanted was to be with his beautiful wife. He adored my grandmother, loved her to the end of the earth," she told KERO-TV.
He was 90 and she was 87, and they met at a bowling alley in Bakersfield in 1952, getting married in the same year.
When civil engineer Don worked for the US Army, the couple spent some time in Germany, where they adopted twin 18-month-old boys from an orphanage.
They returned to Bakersfield, where she worked as a nurse and he owned his own engineering firm.
They are survived by one son and five grandchildren.

A:
Even in death, a couple married for nearly 62 years were inseparable.
